Error when rating tracks

[Corliss Rain]

I'm suddenly getting this error when rating tracks. Just started about an hour ago and I haven't changed anything in my settings. I tried restarting both the program and the computer when restarting the program didn't help.

I think its probably related to a highlighting rule against playlists. This should fix the issue:
