SOLVED: Jellyfin doesn't display favourites properly

[kandykarter]

This is still happening in 10.10. I thought it was Kodi Sync Queue and/or Infuse Sync Queue, but it still happens when both are uninstalled. I thought it might have had something to do with using Jellyfin4Kodi in Native Mode, but having switched to Addon Mode it still occurs.

It seems like the trigger for removing movies from favorites is the addition of new movies to the collection. I favorited 8 movies before I went to bed yesterday, and a movie was added overnight, all of my favorites are gone. There is nothing in the logs that would appear unusual.

I've stopped actively USING the favorites feature (Kodi widgets do not point at favorites anymore because Favorites have become unreliable, switched to a watchlist in Collections) so I'm really baffled. I thought for a while Kodi was doing something to confuse Jellyfin about them, but I'm unconvinced.

Am I really the only person having this issue?


[EDITED TO ADD: This problem appears to have been caused by NFO settings. In Dashboard>Libraries>NFO Settings, I changed "Save user watch data to NFO files for" from my user to "none", this problem appears to have vanished.]
