I have my “TV Shows” library set up in an odd manner. Rather than have a single folder with all my TV shows, I have 27 folders in the library. This is so that I can sort my shows into sub-folders based on letters and numbers.
I had just a single show in my /Shows/Z folder.
It was in the subdirectory as /Shows/Z/Zenshuu (2025)
After a few episodes, I decided I didn’t like the show. So I deleted the show. However, since the /Shows/Z folder was now empty, rescanning the library did not remove Zenshuu from my library. It still showed up in Plex.
I was able to fix this, by recreating the Zenshuu (2025) folder, leaving it empty, then rescanning. Zenshuu was removed and then I was able to delete the folder.
This does however reveal a bug. If a folder in a library is empty, scanning the library will completely skip the folder, but in doing so, will not remove any shows that were previously in that empty folder, leaving ghosts.
