Question: Are you using the Plex Movie
scanner & agent? It is required for Editions. To check, edit the library & choose Advanced. You should also see a prompt to “upgrade the libraries” if you are using a different agent/scanner.
Naming looks spot on. It is OK to have both in the same movie folder.
Try the Plex Dance for both movies.
You should not have to do so, but it will force Plex to treat them as new additions to the library.
Move both out of the library, perform steps 2-4, then move them back one at a time, waiting for Plex to recognize the first before adding the second.
