Most movies unwatched again after update

Hello,

The day before yesterday, my Apple TV updated to Infuse 8.3.2, and since then, most of my movies are showing up as unwatched again. When I go to Settings, everything looks correct there; the number of movies and series is correct. The number of series and movies I’ve watched is also correct. But in the library, around 11/12 of all movies are listed as unwatched. Unfortunately, I have no idea why this is happening; the problem only started after the update. Everything is still correct for series.

I tried restoring a backup from iCloud, and everything was correct again for a few seconds. Unfortunately, it only lasted a few seconds, and then most of the movies were displayed as unwatched again. Does anyone have any idea how I can fix this? I would hate to have to mark all the movies as watched again manually.

It’s an Apple TV 4k 3rd generation with 128 GB. tvOS is up-to-date.
