Library update not working

Hi. I don't know if there already is a Topic about this. I couldn't find it

I added new episodes to a couple tv series today. But update library is not working
No new episodes added.

I tried adding them manualy. This worked with the cleveland show. Only no mediainfo. Or title.

And I tried that with the simpsons, but I got a pop up that said "No info found"
So the new episode doesn't appear in my library.

Is anyone else having the same problem?
