Movie showing IMDB rating in IOS (iPhone, AppleTV) instead of the usual Rotten Tomatoes?

I just added a new movie and for some reason even though it’s pulling meta data from the same place it’s showing the IMDB rating instead of the usual Rotten Tomatoes rating. Any idea why this is and how to force it? I checked my settings for the Agent source (Plex Movies) and it’s set to Rotten Tomatoes but it seems to be ignoring it.

same problem here, rating is set Rotten Tomatoes, but display IMDB
