Try naming the shows files The Magilla Gorilla Show as per the name on tmdb and see if it helps.
You will likely need to preform a full plex dance (all steps)!
EDIT: I tried to match the show manually using The Magilla Gorilla Show and Magilla Gorilla, both failed, even using a year hint. I had to use a matching ID to get it to match The Magilla Gorilla Show {tmdb-11167}.
