Try creating a collection in the web ui for any two movies that have not been part of your collections in the past. If that collection shows up I'd start doing what sasaba describes. If you can't even get a new collection with two random movies to work then I would hold off until that is figured out.
Ok in this case you are right! when i set a complete new collection (movies they dont have anything to do with another then the collection appear in films.
When i want to create a existing collection (with the boxset tag)this collection would be ignored.
The funny thing on this side is that when i create a manual collection with a bunch of movies this collection would be save on the server as Iron Man Collection [boxset]!!!!
What the hell is this! A bad joke from the developers or only to demonstrate their "Uh i am the developer and you have to do what we are say!!!"
In any way this shit makes no sense to ignore the self created [boxset] tag but create the same [boxset] on the server.
This is not listen to the community or something else. Sorry but this is so big bullshit i can´t understand!
Sorry for be a bit pissed of there are some great people in this community, but this case is not the way it could go on and far away from compatible to other systems like Kodi or something else (they use the <set> string in nfo, which is the best way in my opinion.
What should bebetter on put all my movies without collecting or sorted in folders than the old way. Hm?
Now to see my "allready" created collections, i have to delete them completely and put all my collected movies unsorted in any folder. Then i have to create them with the web ui. No posters or fanarts in the correct movie folder.
I think the way of a good collected media is to have all the information i need in the folder itself. Not on the servers folders!
