On the off-chance that someone else runs into this issue, it's fixed in MMW test build 2024.2.0.3154, released yesterday.

My thanks to Ludek for sorting it.

Hi,

I noticed a similar issue reported, which you said is fixed in 2024.2

viewtopic.php?t=107623&hilit=Tab

Do you think this might be the same root cause?

Edit: And I meant to say that, as mentioned, the column corruption also happens when running the Debug version of MM24, but not when running DebugView.

Edit: Never mind, I just tried MM 2024.2.0.3150 and this issue persists.

I've been trying to reproduce and can't. No tab is altered by another tab. Can you please capture the issue in a debug log (step 4b) and attach the log to a Support Ticket: viewtopic.php?t=86643

If you can do so with the latest 2024.1 release it would be best.

It's been a couple of months running the debug version of MM, and I can still reproduce, but not when DebugView is running at the same time.

I've also concluded that the problem is not limited to the Music tab. It's cross-contamination between ANY tabs that happen to be open when MM is run. I generally have tabs open for 'Music', 'Films' and 'TV', and both the 'Music' and 'Films' tabs sometimes inherit the columns used in the 'TV' tab.

I also have 'Path contains' filters set up for multiple 'Films' tabs, and those filters get replaced by those from another open tab.

So yeah, problem is more general than I first thought, but I can't capture a trace for it.

Except occasionally they're automatically set incorrectly. That's the issue.

Sometimes (not always) on a restart, the columns change as described. I can change them back manually, but it keeps happening. All the affected files are of Music type. It happens for the columns for Music/All files, and Music/Albums.

I have other Film/TV Series files that are listed under Films/Series in the tree as you'd expect, and they seem to behave.

The columns are automatically set based on the Media-Type.

Please capture the launch of MediaMonkey, the changing of some columns, the close and then subsequent launch where it reverts the columns in a debug log (step 4b) and attach the log to a Support Ticket: viewtopic.php?t=86643

I updated from the previous latest release, 5.something, I don't recall the full version number. I didn't manually save the old database, so I assume that's overwritten?

I did manually adjust the columns, but my issue is that those changes don't stick. After closing then re-opening MM, the columns revert to a set that look intended for Type = TV, not Music.

What did you update from and do you still have the old database from that version?

You'll need to manually adjust the columns to fix this.

Thanks, but Type = Music already for all these library entries, and the scan is set to use Music manually as well

The columns are automatically set based on the Media-Type.
The “Type” of a track is written to the database during scanning.
If you select all affected files in MM and change them with “Properties > Type: ‘Music’, you will automatically get the desired columns.
When scanning (File > Add/Rescan...) make sure that the media type is set to automatic. If this does not work properly, you may have to select the desired type manually.

Just updated to MM2024 and noticed that my library listing for 'Music/All files' (Music type) is displaying the columns that I've selected for Series/All videos (TV type) instead.

So instead of Title, Artist, Album Artist, Album, etc., it's showing Title, Director, Screenwriter, Season#, Episode#, etc.

I can manually change the columns displayed, but when I close and re-open MM, it reverts to the wrong columns.
