I saw this post,
However, I'm only seeing this with one application which is weird.
I can drag and drop to other applications and the issue does not happen.
It's only when I drag the list to Mixed In Key for processing.
Link: https://mixedinkey.com/
The list will disappear and I can will refresh after.
This is a question for the target application.
If that tells the source application that the data is moved and not copied, then the objects disappear from the source application.

Windows Explorer integrtation not installed
Add two or more files into Mp3tag
Drag one file out, to a Windows Explorer folder or in my usual case, Audacity
File disappears from list in Mp3tag
Refresh Mp3tag list with F5, file reappears in list
In File > Options > General, I have enabled Keep moved files in file list option so I believe this should not be happening and it is a bug.
The official answer and "still no bug" from the developer (for the example target application "Audacity"):
I've reviewed the code in question again and it still holds. Audacity returns DROPEFFECT_MOVE at drag and drop without any modifier keys pressed and DROPEFFECT_COPY when Ctrl is pressed.
When the target app of the drag and drop reports that files are moved, I have no other chance than removing the files from the file list. I have no indication of where the files are moved to and would end up with orphaned files on actual moves.
One option to circumvent these problems would be to disallow move …

What happens if you press CTRL to drag & drop files to "Mixed in Key" as suggested here:
You can try holding the Ctrl down when performing the drag and drop operation. Does this help?
I'll give this a try and see what it does.
What I'm thinking is it's possible MIK creates temp versions of the files which cause the condition.
I can refresh the list and everything is normal again, I just found it weird that only dragging the list to that application does this.
All the other apps I use to process tracks don't cause this behaviour.
For instance I can drag to Serato DJ for track analysis. It could drag the list to MLT (Music Library Tool) for genre analysis and no issue.
It only happens when I drag to Mixed in Key.
I'll try using Ctrl to see what it does.
It must be something MIK is doing because none of the applications where I drag the list from mp3tag to them cause the list to disappear in the mp3tag.
I'll do some testing and update this.
