Mac Music Problems Changing Smart Playlist and Playlist Folder Names
I've just started getting this odd problem. When I edit the name of a smart playlist or a playlist folder then the name change shows up OK at the top of the playlist when I'm looking at it but the change doesn't happen in the sidebar, where the playlist shows the name before the edit. If I quit Music and re-open then the name reverts to before the edit.
It's not all smart playlists and the only common theme seems to be that it's a problem with empty smart playlists (e.g. condition such as all 5 star tracks played less than 76 times is empty cos they've all played 76 times), but once the list is empty it sticks. i.e. in the example above I can edit the smart conditions to <78 times, which populates the playlist but if I change the name it exhibits the above behaviour - i.e. doesn't display in side bar and reverts both the name change and the smart conditions on restarting Music.
Additionally, when I make the name change then track-history metadata stops updating. So after I've edited the name as above then the tracks which play subsequently (in any playlist, not just the one edited) don't update their play count or last played date. I have to quit Music and re-start at which point the metadata updates as expected, but any play data since the edit and before Music was restarted are lost.
I've tried quitting and restarting Music, rebooting the Mac, booting into safe mode and run disc utility first aid. It's only just started happening today, so it's not related to a software update, unless a security update went in recently (I have those on automatic).
I have the same problem trying to change the name of playlist folders. Non-smart playlists seem to be OK, but I don't really use them so haven't spent as much time testing them.
Thanks in advance for any help.
