Does the directory /Volumes/DM Passport/Movies/Final Destination Extras/ still exist? If so, move it to a location not visible to the Plex scanners (out of the /Volumes/DM Passport/Movies/ directory).
Then Plex Dance the movie and extras.
The extras were in a non-standard location, /Volumes/DM Passport/Movies/Final Destination Extras/.
They have since been moved and renamed a few times.
There might be some incorrect information in the Plex database. The Plex Dance clears out existing information for the movie, and starts over, like you’re adding the it for the first time.
