I have all of my static playlists customized with descriptions, custom displayed fields and specific display views. They also all export static copies. I can't figure out what triggers it but I keep opening them and finding that they have completely reverted back to default settings. It doesn't happen every time, and it's not all of the playlists. I just notice a few here and there.
Sorry, I don't have any more details so I understand if nothing can be done at this time.
