I have a Plex Server on my Ubuntu 18.04 box. The movies are on a 3TB HDD which is not even 1 year old. I have about 280 movies and Plex recognized all movies but sometimes if I hit scan library, it starts to find media files like Media 0034, Media 0038 etc… As I can see the preview picture, 3 of them are the same movie and it downloads a totally different metadata. It looks weird when I can see strange movies on my TV with my family. I don’t really understand what is happening.
I tried to update Plex on my server, update Ubuntu but nothing. I have a newer update and I will install it later tonight but I don’t think it will solve my problem
After it finished scanning the library and it downloaded the metadata, I hit Scan Library again and it corrects itself.
Edit your library
go to the ‘Add Folders’ tab
look at which path(s) you pointed the Plex library
They should only point at folders with your media files.
They should not point to the Plex data folder.
Nor should they include folders where temporary files from any downloading/torrenting/unzipping/ripping procedures may (temporarily) be present.
