I have been having a more widespread but similar problem that seefilms introduces. As it had been marked solved, I messaged Volts and he/she was kind enough to help me. I am not using the new Plex Movie Agent and have been running for 7 years via IMac to a Synology NAS. In my case, for several months, every ripped movie or TV show has not had the correct title, though all other metadata has been correct.

and after scanning here is the result within TV Shows:
and to demonstrate that all other metadata worked, here is episode 1:
After help from Volts, I found a similar fix to the one shared with seefilms only as I am using an older agent, I needed to go under the TVDB agent where I found a similar priority listing:
After changing the order of these:
and doing the Plex Dance (delete files, clear the recycling bin, scan, replace the files and scan again, the problem is solved:
Thanks again to seefilms for the original post and Volts for detailed help!
