If you had the movie already added to Plex, you might need to perform a “Plex Dance” in order to clear the wrong data from the initial match:
- move the files outside the scope of that library
- scan the library for updates
- empty trash and clear bundles
- fix the file names and return them to their target folders
- scan the library for updates again
