"Show In Playlist" shows every playlist folder
I restored my very large library this week (related to my iPod Classic freezing). I dumped the itl file, started iTunes and imported my Library. After this process was done I noticed that when I right-click a song to see what playlists it is in, the pop up displays EVERY playlist folder in my Library. The individual playlists that the song is actually in are also displayed, but this huge list of folders obscures where they are. I am an old hand at iTunes and have never seen this. Coincidentally, when I select any playlist folder in the playlist column it displays a song count equal to my whole library (as opposed to just the count of all the songs in the playlists inside the folder). What happened and how can I fix it?
In the screen shot below, the selected song is in 4 playlists (circled), but all playlist folders are displayed.
