Synchronize Remaining Items

Hello, Everytime I synchronize, I get this message about 2 remaining items. Any idea how I can find out which ones of the watched movies are failing to sync?

Thanks!

Further to my post, here’s what I see when I go to the Synchronization page.

This happens when a TMDB ID is not available on tract :confused: Normally it should skip this fetching when it fails.

I will have a look.
