Roon rescanned my music library (not sure why) and when done my playlists are no longer complete. The playlists show the correct total count of tracks and the number present (such as “9 of 15 tracks, 63 minutes”). I forced a rescan but it did not reveal the missing tracks. Every playlist is missing a few tracks out of 15 or so. How do I restore my playlists to their full count?
