Duplicate movie (instead of versions), with collection to add insult to injury

Thanks, I tried that now and unfortunately it seems the only effect it has had after triggering the tasks manually is that the name of the superfluous collection is now in German (correct language for content in the German library) instead of English. 
Still results in two entries for the same movie that then has the version dropdown within as it should.

Will have to wait and see whether the next JF version fixes that and the flood of other library listing bugs, no matter when that will finally have a mainline release.

The problem probably stems from how there's a sequel to that old movie in the works, TMDB already has it on the books and the collection tag for it, JF sees two files for the first movie and somehow draws the wrong conclusions.

Ah.  That's ok then.

The only other suggestion I have is to remove the IMDB ID from the folder name.  Jellyfin does not make use of IMDB for metadata, but we do use it for identification on TMDB since TMDB maps IMDB IDs to TMDB IDs.  BUT, sometimes that mapping is wrong.

Interesting, I now have a similar case with a movie where there isn't a sequel in the works, it generates a folder instead of a boxset around it and the duplicated movie phenomenon happens and the movie versions then appear in a dropdown, but the featurette gets swallowed.

Code:

"F:\Video\Contact (1997) [tmdbid-686]\Contact - [A Personal Voyage Cut].mkv"
"F:\Video\Contact (1997) [tmdbid-686]\Contact - [Standard Cut].mp4"
"F:\Video\Contact (1997) [tmdbid-686]\Featurettes\Carl Sagan - How Would We Communicate with Alien Life (Royal Institution lecture 1977).mp4"

BTW: I usually include the IMDB ID as well, since TMDB uses separate incremental IDs for movies and shows, often leading to false mappings, especially for more obscure stuff.
