Adding new file type of same movie results in new movie in library

Server Version#: 1.29.0.6244
Player Version#: 4.93.2

Sometime in the last few months, Plex stopped recognizing multiple movie versions. I’ve been converting old .avi files to .mp4 or adding HD versions that previously I only had SD, and when I add them to the library, they’re showing up as newly added movies. Furthermore, if I go into the Movie library, they show up right next to each other with all the same metadata and info. I can manually merge them, but it’s tedious and I’ve never had to do that before. Also, all these old movies now show up on my home page as Recently Added, when they’ve been in my library for years, which is also annoying.

Besides regular updates, the only change I can think of since I started noticing was that I finally gave in to the constant upgrade notifications and upgraded all my libraries to Plex libraries a few months ago, and this might be the first time I’ve added new files for the same movie since then.

Inspect the Plex media info XML of both copies.
copy the XML property guid="... (all lower-case) and its content to here.
Compare them.

Original file:
guid=“com.plexapp.agents.themoviedb://334543?lang=en”

Newly added file:
guid=“plex://movie/5d776b9123d5a3001f511cfb”

Definitely seems to indicate that it is related to the switch over to using the Plex agent since the older file references TMDB. So how do I fix this so it stops happening?

Indeed.

Refresh Metadata of the whole library. The conversion from old to new agent is not complete without this step.

Refreshing Metadata for the full library worked. I tried adding a few more duplicates, and they were recognized as such and didn’t show up in the Recently Added section.

Thanks!
