Metadata not updated

[Tsch3ns 18]

Hello,

after migrating my database from DS918 to DS425 and copying all movies to the 425, lots (if not all) movies miss metadata (pictures of actors), see attachment. I already tried to update the metadata of the whole library without success. I have to update each movie individually in order to get the missing data. Whats wrong here?

Emby Premiere Server 4.9.5.0
