Odd recurring issue - Musicbee overwrites Genre tags on ALL files without asking
I've been using Musicbee for several years and it's great, other than this one weird problem. I have a side panel set up to show the genres. Every once in a while (with no apparent input), it will overwrite the genre tag on all 2,000+ files to show "All (50 items)." With '50' being the number of genres that were present before they were overwritten.
This has happened maybe 5-10 times. I can't find anyone else with a similar problem. It does not ask. It does not confirm. It just writes new tags to every song in my library. 'Undo' does nothing. The only way to fix it is to replace the files with a backup. It's pretty tedious.
I set this panel up under "Edit Preferences > Layout(1) tab > Arrange Panels button". It's the "Left Main Panel" labeled as Library Explorer, grouped by Genre. Musicbee version 3.5.8698.
Any thoughts? I disabled the ability to edit tags from the main window, but the problem persists.
