All of these mp3s have APE tags. I realize this is an issue but I have Mp3Tag set not to read the APE tags because I need to access the actual tags right now. I refreshed reading the tags several times and nothing changes.
Now, if I click on an individual track in the tag window then all of a sudden the entire tag shows. That is great but I cannot do this for 30K files.
Any suggestions?
Have a look here from the Faq
Options > Tags > Mpeg defines how Mp3tag deals with tags from MP3 files and Options > Tags > Ape, Mpc, ... is responsible for all other supported formats (Monkey's Audio, FLAC...).
If you want to transfer APEv2 tags to ID3v2 and ID3v1 tags for example, you select the reading of APEv2 tags and the writing of ID3v1 and ID3v2 tags. After applying the settings by pressing the OK button, select the files which should be re-tagged, press Ctrl+X and then Ctrl+V. If you don't want to remove the APEv2 tag format after the transfer, press Ctrl+C instead of Ctrl+X or simply select the tag formats to write from the Mp3tag options, select the the files and click on 
.
Thank you but I don’t want to transfer the APE tag info because it is limited to gain adjustments only. I just want the ID3v2 tags to show because those are the relevant tags.
I also do not want to remove the APE tags at the moment because I still need that info to revert the gain changes.
What did you set - Options - Tags - Mpeg to?
There you can for example set to read only ID3v1 and v2 and NOT APE
That is exactly how I have it set, to only read ID3v2 tags because my files have no version 1 tags as they are useless these days.
Oke whatif you select All songs - CTRL + A and then Press F5 (refresh) does that do what you want? Or use CTRL + T to read the tags.
I am honestly at a loss what is the issue.
Edit: Can you post a screenshot? Use that button in the edit post which looks like a HDD and Up Arrow to upload a screenshot.
Sorry to bother you again, can you click on one of the files, that DOESN'T SHOW TAGS and the press ALT + T, that will show the extended tags, and post the result of that?
Oke and to clarify in Options - Tags - Mpegs. You have enabled under READ - ID3v1, ID3v2 and Ape?
No, I don’t have it reading the APE tags because I was told in the past not to if I wanted my ID3v2 tags to show. They show, but only after you click on the individual tag and I am sorry I don’t have time to do that 30K times.
I fully understand. But experiment with those settings, under Tags - Mpeg
What you also could do, is CTRL+A, select all songs and then click ALT+T. Does they show then?
OK, that did it. Select all then ALT+T. But why should I have to do that? 
I also find it strange. You should play around with the Tags settings.
What does your write - Tag settings is set to?
And remove?
Edit: test on a couple of files, not your whole lib
I did test it with all kinds of setting like you suggest but it changed nothing. I have all APE deselected in every option. No read, write, or remove. But the minute I deselected to read the APE files and refreshed that is when I found clicking on an individual track would then make the tag visible.
Try Ctrl-T to re-read the tags and see if you get more data displayed.
Alternatively, could you switch off the library function, restart MP3tag and read the files again and see if that helps?
I already asked him to do that @ohrenkino
Sometimes, suggestions have to be uttered several times.
As selecting the next file and pressing Ctrl-T has the same effect ( = the tag is read again) and we have to rely on that what a poster says is true, it may be that some kind of interference blocked the execution of the originally intended action.
I just find it strange, that the tags are NOT displayed on READ, but only on ALT-T or a click
Just an idea @Ronstang Where are those files located? On a internal drive or on a USB stick or a Network Attached Storage device? It could be that the speed of the device prevents the reading, but that is just totally guessing
What I am saying is true. I am neither an idiot nor a liar. This has happened before due to my APE tags, that I am working to remove actually, but it was not as big of a deal because I was working with only the tags from one artist or a few albums but now I am working with the entire subset of my collection on my phone. AND, this is repeatable, over and over.
I have my music on two different internal drives and both of them are 2TB NVMe SSDs so this is not a drive issue. My entire drive system in this machine is lightning fast with other SSDs and two 16 and two 18 TB Toshiba server level drives on a SAS controller. Speed and latency is not the issue here, but thanks for thinking.
It has me confused too as to why just rereading the drives by hitting F5 does nothing but selecting all and then using ALT-T does what it needs to do.
All the tags were displaying so I did a test. I switched to another folder on a different drive and then switched back to the folder I was having trouble with and upon the reread all the tags show up now so this is confusing, really confusing. It’s been a few months since I messed with my music but this behavior has happened before where clicking on the file displays the tag and then subsequent rereads they show from then on.
Oh, and I have a couple tracks that instead of the file icon on the left edge I have a red X. What does this mean?
