Problem with Media Player

Last night everything was working fine. Today I turn on the apple tv to find that no thumbnails are shown for the recent watched, i have duplicate items in the media player top bar: two search, two library, my tv shows are not recognized, it is a mess.

What can I do?

What I did:
Uninstall/install Media Player: everything was the same.
Restored from a normal back up I had from 2 days ago, everything is normal.

Do I need to make a back up every day?
