That is weird.
Clear the caches.
Can’t hurt - might help.
I’ll edit again while you’re - away:
If you’ve been fiddling with names while Plex has been watching - and when you get back from a cache dump to find it’s still not happy - do this with the whole show:
The purpose of this is to remove all cached metadata and xml data for an item that Plex usually keeps. This helps when you want to “start from scratch” for particular item
move all files for the media item out of the directory your Library is looking at, so Plex will not “see” it anymore
scan the library library (to detect changes)
empty trash
clean bundles (in menu next to server name, when accessed under ‘More’)
double check naming schema and move files back
scan the library
Support articl…
EVERY STEP
IN ORDER
or it just won’t work.
