SOLVED: Collections are duplicating

[csavage]

0. I have only been able to find posts about collections not showing artwork (the issue I originally had, but not anymore).

1. I started off not being able to get my collections to show artwork, but they were generating correctly. I added the TMDB box set plugin and this started fixing the problem, however I started getting duplication of all collections, one clone had artwork, the other didn't. I have removed the TMDB boxset plug, deleted the Collections folder many times, and rescanned the library so that it would regenerate the collections and am still getting the same issue. I have also tried with the plugin installed and the generate collections check box unchecked in the Manage Library section of my movies folder, still the same effect.

The version of Jellyfin you are running: 10.10.7
Your installation method and platform: Windows installer, Windows 11
What client(s) you are using and how the issue manifests: Web, showing duplicate collections

The following images are without the TMDB box set plugin installed.

In the Collections folder:


In the Movies folder:

This happened b/c you selected "Strip Keywords from Title" in the TMDb Box Sets plugin, which made a duplicate entry without the word collection. There are several ways to fix this, I'll outline one method below.

1. Unselect "Strip Keywords from Title" option from the TMDb Box Sets in Dashboard->Plugins.
   
2. Shutdown the server
   
3. Delete all collection folders in your Jellyfin data directory \jellyfin\data\collections (you'll see all the collection folders in here)
   
4. Restart the server
   
5. In Dashboard->Library go to your Collections and trigger a scan of your library. This will remove all the folders you just deleted.
   
6. In Dashboard->Scheduled tasks manually run the Scan library for new box sets. This will recreate your collections.

The issue is still occurring though, even without that plugin installed. I have uninstalled it and am still seeing the same issue. Is that option also somewhere in jellyfin as well?

I gave you specific instructions on how to solve. Did you try that or something else?

Check the settings for your movies library & see if you have "Automatically Add to Collection" selected. If you are using the TMDB plugin for collections make sure that you deselect "Automatically Add to Collection" or you will get duplicates

I didn't try it initially, no, because I no longer had the plugin installed and the issue was still occuring. Just did it and reinstalled the plug in and it's working as intended though, so thank you for the assist!
