If Plex has a “mis-match”, you sometimes have to convince it to actually clear that mismatch from its database.
The procedure is called the Plex Dance.
btw. Plex is not using the episode title from the file name. It will solely go by season and episode number and look up the title in TheMovieDB.org
So your files better use the identical numbering and ordering as they use on TheMovieDB.org (or optionally the one on TheTVDB.com)
