Multi-image Collection poster only uses three posters

[cajomo123]

Server Version#: 1.41.5.9522

I have one collection in my library where Plex refuses to load more than three individual video posters in the multi-image collection poster, which forces one of the video posters to repeat in the collection poster. The collection currently holds six individual videos.

Have tried:

• Changing the collection poster manually then back to an automatically generated multi-image poster (this will update the multi-image selections, but keep them at three unique with one repeating)
• Deleting and recreating the collection

This is the only collection I have with more than three items where this is happening.

Compare to other collections I have created, which only repeat in the multi-image collection poster as necessary.

Through your testing above, is it duplicating the same poster each time? If so, try deleting the collection again and:

1. After deleting it, head to Settings → [Select Server Name] → Troubleshooting.
2. Optimize the database and clean bundles.
3. Recreate the collection manually, this time leaving out the movie whose poster was duplicated.

If the collection poster is created from four unique posters this time try adding the problematic movie back to see if they remain so after.

Even if it’s not the same poster being duplicated each time you still might want to try the steps above. Kind of a collection Plex Dance.

The duplicated poster in the multi-image collection poster is not always the same. Following the instructions above, I optimized my database and cleaned bundles. This did not directly solve my issue (though there’s no way of knowing if it was perhaps a catalyst).

I did delete and recreate the collection, adding each movie one at a time to monitor the progression of the multi-image collection poster. In the end, a collection poster with four out of six unique videos was generated, so the problem is resolved for now.

Some interesting behavior though–if I try to edit the collection poster, and then return to an automatically generated multi-image poster, the poster will contain one duplicate. At that point, the generated multi-image collection poster will always contain one duplicated image until I repeat the steps of either:

1. Remove all but three of the videos from the collection, then re-add the rest one by one, or
2. Delete the collection entirely, then recreate, adding each video one by one.

There appears to be some bug in the ~re~generation of the multi-image collection poster thumbnail that is not evident in the initial generation of the thumbnail, where it has the potential to continuously duplicate one poster selection in the multi-image thumbnail.
