Playlist Now Empty

Hello, I'm trying to track down an issue with playlists. Looking at the playlists in the side bar, they look to be fine with the number of songs in parenthesis. But when you actually click on the playlists, there are no songs in them. Has anyone seen this and/or does anyone know where the playlists actually live? I am needing to search and see if there is a backup of this file in order to hopefully restore all of them. This is on a system with multiple users connecting to the same server.
From my Googling, it looks like the playlists are located in the database file on the server and can be extracted. If anyone can confirm or deny this, or has guidance on restoring, please let me know. Thanks for any help!
