Almost all TV shows should be in the format
show name - SxxEyy - Episode Name.ext
So your episodes should be titled:
Reno 911 - SxxEyy - Episode name.ext
The episode name is optional.
Plex needs good naming to work correctly:
. . . . . .
TV Shows <- The TV library points here
_______ShowName (year)
____________Season 01
__________________ShowName (year) - s01e01 - Optional Name.ext
__________________ShowName (year) - s01e02 - Optional Name.ext
__________________and so on for the shows in season 01
____________Season 02 <- just like Season 01
____________Season 03 <- and so on for each season
____________Season 00 <- or “Specials”
__________________ShowName (year) - s00e01 - Optional name
__________________ShowName (year) - s00e02 - Optional name
__________________and so on for each special
Note: the eXX part of the specials must match EXACTLY what is found in TheTVDB
You can try other setups BUT Plex is very picky about TV show structure and it is best not to fight the great Plexisaurus.
Plex is great about all of my other shows but I think the “911” in the title tricks the code, so it’s not reading the second number as the season and episode number. I think the best solution would just be to remove “911!” from all the titles, I was just hoping there was an easier solution: something I could do on the Plex app to “teach” it to read that as part of the title.
you might not like it, you might even hate it, but if you want it to work then you need to rename them to plex compatible format as per Elijah’s example above.
There are very few things easier to do than fixing the naming of a series, If you use Windows then FileBot will almost do it for you using the “Plex” format string. If you use another OS then there are tools that are almost as easy.
As far as your “other” shows goes: They may work for now but, if they are named as badly as your example, they could stop working at any time. Plex tries very hard to match almost anything and it succeeds more often than I would expect but it is best practice to use the format Plex wants.
BTW: I have yet to find any program that will not correctly match a series that is named the way Plex wants.
