I see, well I don't have many tips, but could you try to make a collection manually, just to see if the plugin is at fault or something else?
To keep things simple, I'd advice you to disable the plugin while testing.
Find a collection of at least two movies that you own that is listed at themoviedb.org, select the movies and proceed to select "add to collection", name the collection according to the name at tmdb, hit refresh and it should automatically fill out the metadata.
Then, if all works as it should, you can go to your movie library and the newly created collection should be there with a number in the upper right corner of the thumbnail corresponding to the number of unwatched movies in the collection.
