Hi Michael,

It's difficult to diagnose but could be related to the cloud database migration in v1.60.

Here are some ideas that might resolve the issue:

1. Logout and login.
2. If you've synced your library to the cloud, try Settings/Debug -> Reset Local. This will delete your local database and re-download it when you login.
3. Alternatively, export to XML (for example) and then Reset Local, then re-import your library from the XML.

Let me know if either of these options help!
