List of files disappears when I'm in positions 1-2-3 from the top

Currently on 3.18, 64-bit. I had a list of 27 songs. I was editing titles etc. and was proceeding to add artwork. I started at the bottom and was working my way up the list. When I got to position 3 and clicked on it the whole list, except for #1 disappeared, and that was not selected. Of course this mean I need to reload the entire list of 27. Sometimes, if I load the artwork in #1 first than the list doesn't disappear as I work my way up. A final point, this seems to happen every other build. I can't sure of that fact, however.

What do you mean by "clicked on the whole list"?

When I click on position 3 to add the artwork the entire list, except for position 1, disappeared. Additionally, position 1 was not selected (or active) and I had to click on it to select it.

Sorry, my sentence would have benefited from a comma after click on it.

I still have no clue what you exactly are doing.

If you want to add the same artwork to all of the loaded files, you have to select them all with CTRL-a (or Menue Edit->Select all files). Then click with the right mouse button on the cover field in the tag panel and make your selection ("add" to add covers from a file, "paste" to add covers from the clipboard ). You then have to save the changes.

I first understood your original contribution to mean that you first selected all files from below with the keyboard and pressed the Shift key and the arrow key up. Then you "clicked into the list" (which would have undone the selection with the left button) and the files all but the 1st loaded file simply disappeared? Or do you mean that the selection has been deselected (which would be the normal action with a left mouse button click)?

I just loaded 27 files into MP3tag.
I selected 1 by 1 from the bottom and added for each a picture file from the clipboard.
I reached the top of the list without any changes to the extent of the list, that is: all 27 files were still displayed in the file list.

So, where did I do something different from you?

That is the same process I used. Sometimes I get that result also. Other times when I get up to positions 4 or 3 and click on it, the list disappears except for position 1.

Actually, I haven't got a clue what might be the cause.
Usually the file list gets updated when you apply a filter or press F5 to update.
But never in the middle of editing.

So, just another shot in the dark:
What happens if you go through the list from top to bottom?
Do you edit files locally or in network location?

Something I've tried, plug the artwork into position 1. Then I go back and work my way up the list. That's had mixed results, but usually works.

Could you narrow down that a little more like when everything is OK and when it is not?
Currently, I cannot reproduce it.

Pardon the long post, but I’ll try to describe a bug that seems to occur with every other release of Mp3tag. I am currently on 3.28, released on 11/15, and it just occurred again this morning. This describes the specific steps I did.

I process my mp3 files thirty at a time. I get them cleaned and put them in a folder. I select them all and click on MP3 in the Windows explorer list. This opens Mp3tag and loads the 30 files. In Mp3tag I usa Ctrl-A & select them all. I click on the “Filename-Tag” button. From there I go to Year and select blank, then Genre and select blank, then press the File icon. I sort them by Filename. I add the year and genre data for each file. Then I start at the bottom and add artwork to each file. As I work up the list I get to number 1. When I click on it the preceding 29 disappear from the screen and I’m left with only the first file displayed. So, I need to return to Windows File Explorer and reload them into Mp3tag again.

As I mentioned, this seems to be happening every other release/update, but I haven’t documented that to be sure.

At one point, I could trick Mp3tag into not doing that by going to record #1 first, adding the artwork, then going to record #30 and working my way up. That didn’t always work, however, so I stopped doing it.

I am running Windows 11 Pro.

There is the button F5 to reload the files.
Does that work?

What puzzles me:
AFAIK MP3tag it does not hide or show files unless the user triggers MP3tag to do so.
So which user interaction happens between editing the last file and selecting the first?

The reload button does not reload the files when this occurs. There is no user action taken. This morning, I loaded the artwork into file #2, clicked on File. Then I clicked on file #1. That's when the other 29 disappear and F5 does not reload them.

Does this mean that you click on the column header? Or do you click on the Menu FIle?

This looks to me like you have changed the working directory.
Do you hit Del somewhere along the line?

I clicked on the blue file icon right below the menu word file. This is why I'm reporting it as a bug. Saving a file after editing and moving to the next should not cause the other 29 to disappear or, as you suggest, change the directory.

I was just guessing from your description.
At least we got settled that you click on the save button.
Now it would be nice if you could post a screenshot of the initial setup and then a step by step description with reference to each called function on the way until the problem occurs.
Because up to here no-one could reproduce what you experienced.
And - as you say that you have experiences as former software department manager - you will know how important detailed descriptions are to narrow down the root cause.

  1. From Windows explorer I select all the files
  2. Right click and choose MP3 option. 2a. Files are loaded into Mp3tag.
  3. Ctrl-A in Mp3tag to select all.
  4. Click on the Filename-Tag icon.
  5. Go to Year dropdown and select Blank.
  6. Go to Genre dropdown and select Blank.
  7. Click on Save icon.
  8. Repeated steps for each title, starting with title #1 enter release year into year, press Enter to move down to next title & enter release year...etc.
  9. Repeated steps for each title, starting with title #1 enter genre press Enter to move down to next title & enter genre...etc.
  10. Select title #30 (by clicking on the note icon) & from my artwork folder drag the title's artwork to the artwork box & click Save.
  11. Repeat step for titles #29 thru #2. Note: artwork for each title ranges from about 2kb to about 25kb.
  12. Click on title #1's note icon. At this point all titles except #1 disappear. Title #1 is not selected. Pressing F5 or the reload icon does not reload the titles. If I do click on title #1, I can drag the artwork to it and save. However, I cannot review the previous 29 titles I had done and must go back to the source folder. Then either drag & drop them into Mp3tag or use the right click, chose Mp3tag option.

What happens if you switch off the filter?

To be honest, I had to look up Filter. It has been checked by default, I assume, since I've been using Mp3tag. I've never checked it and wasn't even aware it was there. I can uncheck it and report back in a couple days when I assemble 30 more files.

Even if it is kept on, make sure the filter bar is cleared. Even a space character can impact your file list.

And please note also the Mp3tag Status Bar at the lower right:

"The Status Bar at the bottom of the main window provides detailed information on the number, length, and size of selected and total listed files. If the Filter is active, the total segment lists both the amount of files from the filter result and the total amount of loaded files."
