Just in case you do not have the full correct structure I will paste the guide I have given others here:
…
TV Shows <— The library points here
---------TV Show Name (Year first aired if needed) <— This folder holds the season folders
------------------Season 01 <— This folder holds all the episodes for season 01
-------------------------ShowName - s01e01 - Episode Name.ext
-------------------------ShowName - s01e02 - Episode Name.ext
-------------------------And so on for the rest of season 01
------------------Season 02 <— This folder holds all the episodes for season 02
-------------------------ShowName - s02e01 - Episode Name.ext
-------------------------ShowName - s02e02 - Episode Name.ext
-------------------------And so on for the rest of season 02
------------------Season 03 <— This folder holds all the episodes for season 03
-------------------------ShowName - s03e01 - Episode Name.ext
-------------------------ShowName - s03e02 - Episode Name.ext
-------------------------And so on for the rest of season 03
---------2nd TV Show Name (Year first aired if needed) <— This folder holds the season folders
------------------Season 01 <— This folder holds all the episodes for season 01
-------------------------2nd ShowName - s01e01 - Episode Name.ext
-------------------------2nd ShowName - s01e02 - Episode Name.ext
-------------------------And so on for the rest of season 01
------------------Season 02 <— This folder holds all the episodes for season 02
-------------------------2nd ShowName - s02e01 - Episode Name.ext
-------------------------2nd ShowName - s02e02 - Episode Name.ext
-------------------------And so on for the rest of season 02
------------------Season 03 <— This folder holds all the episodes for season 03
-------------------------2nd ShowName - s03e01 - Episode Name.ext
-------------------------2nd ShowName - s03e02 - Episode Name.ext
-------------------------And so on for the rest of season 03
Note: The year after the show name is only normally needed or desired if there is more that one show with exactly the same name. Check http://thetvdb.com/ if you are not sure and match exactly the name used there. There are some exceptions to this where the year is needed even if there is no other show of that name or if the show does not have the year in TheTVDB.
There are naming methods other than the above that work but this does work 99.9% of the time.
If you are going to use Plex it is best to use the proper naming conventions so Plex makes the best match possible. Trying to force Plex to use other naming methods is just asking for frustration. https://plexapp.zendesk.com/hc/en-us/articles/200220687-Naming-Series-Based-TV-Shows

If your structure is already like this then ignore this post.
If this is not exactly your format then Plex may work with it BUT it also may not and it may partially work.
You are just adding your main TV folder(s) to the library and not each individual show folder right?
This is wrong G:\King Of The Hill\Season 9\King of the Hill - 9x01 - A Rover Runs Through It.mkv
This is right G:\TV\King Of The Hill\Season 9\King of the Hill - S09E01 - A Rover Runs Through It.mkv
G:\TV\ is the folder that should be added to your library. not G:\ nor G:\King Of The Hill\ nor G:\TV\King Of The Hill\
All are not done So when you see the king of the hill daffy duck dexter laboratory they are not done… But things like house md are and the show up funky. Even some that were good yesterday are screwed up today without touching them.
ok well your logs indicate you are adding G:\King Of The Hill\ to the library. so it thinks “season 09” is the name of the show since that is the next folder.
