Problems after migrating to new server

[windbreaker_familiar]

10.9.7. The old server was a slightly older version. I got it working by removing the libraries and re-creating them. This carried over most of the metadata and watch status.

Although another issue I've noticed on my Shows libraries, it now shows Season posters for seasons I don't have on my server. It's very annoying and didn't happen before. How do I get these to go away?
