Check if the TMDB ID field was populated for movies in your library. That ID is needed for the boxset plugin to work. Find a movie and click on the "..." context menu and "Edit Metadata" and scroll down. If TheMovieDB was NOT enabled before, simply enabling it now won't retroactively back fill the TMDB IDs. You would need to refresh the metadata and select "Search for missing metadata" from the drop down. Once that completes verify that the TheMovieDB ID field was populated and re-run the job for the boxset plugin.
