These should be one and the same.
Plex will often not clear the trash if the database is damaged.
If the DB file is healthy, a regular reason that the trash is retained is that not all the paths listed on the “Add Folders” tab of a library are:
- existent
- accessible to Plex server
- not completely empty
There is a third reason cropping up lately, but only specifically if your server is running on a Mac and uses a Synology NAS as media storage: Plex Files Unavailable but they’re not missing - #525 by scuzzbono
