There is no Plex IMDB option to match tv shows so you’re going to have to change that IMDB show id to TVDB or TMDB
Click the 3 dots next to library you want to change in the sidebar – click advanced and change it to TMDB or…
Click the little pencil on the show poster to just change an individual show – click advanced and pick TMDB (Aired)
I’m not sure what the default is so it may already be set to the TMDB
It is a good practice to put the show name along with the “s01e01”
If you are having trouble matching things and want to change your naming structure you can try this tv renamer. It’s free
