I just tested this naming structure in a test library on a test server (PMS 1.18.2.2058):
My TV Shows library points to the “TV” folder. It resulted in the following, once I set episode ordering to absolute numbering:
Since TheTVDB has their absolute order assigned to a single season (1), the “Season 01” folder and “S01” in the filename are important for it to match correctly as such. You may need to perform the “Plex Dance” during the renaming/structuring process, but you may not if PMS didn’t match it at all to begin with.
