I had duplicate movies files for a Movie (DVD and Blu-ray). When I deleted the DVD file and re-scanned the library, I expected the “2” to go away. Instead it has a red “Unavailable” next to it. When did this behavior change? How can I set it back where items will be simply removed on re-scan?
Did you put both versions into one folder or were there different folders for different qualities?
If you delete a ‘top’ folder, which is added directly to a library under the properties of the library, ‘Add Folders’ tab, then Plex considers this folder not as erased but only ‘temporarily unavailable’. You must then remove the no-longer-existing folder from the properties of the library.
