Anyone else getting duplicates "On Deck"?

Version 1.11.0.4666 running on qnap vts-682

no :wink:
unless you mean the same movie in different hubs (e.g. recently added, recently released, best unseen…)

Happens when you have several libraries and have the same movies in them.
(like for instance when you have a ‘4K’ or ‘3D’ library and a regular library)

Or if you ‘split’ a duplicate movie before.

The only cure is to use a different metadata agent for the second library. That way the two versions are different for Plex.
