Plex pulling incorrect film Summary language

Thanks for your help so far, I really thought you had it figured out but unfortunately it still did not fix it. I am utterly baffled.

OK, this movie is matched with Plex Movie and it says it uses english. LOL.

Review the agent settings of the Plex Movie agent, just to make sure.
Should look similar to this, unless you have different preferences in regard to ratings:

First measure to take: delete the local cache for both TheMovieDB and IMDB.

Then reboot your server machine.
Then Plex Dance one movie, to see how it behaves.
