Failing to get metadata of "Stephen King's IT"

You currently cannot do that. Plex will by its current design show all the actual episodes contained in your file.

There’s a feature suggestion to show multi-episode files as a single library item instead.

Display single file multi episode shows in a single item

a way to have Plex display single file multi episode shows in a single item, ex: episode name, Episode 1-2, instead of duplicating it in the display and playing the full file twice. Instead of having to split the files, or only having one of the episodes in the file name, making it seem like im missing something. also: ability to show multi part movies in a way that makes sense, like part 1 and 2 under the same Title, instead of showing it as if there was a duplicate movie.

Your only other alternative would be to simply list the file as a single episode and to manually change the title from Part One to something like Parts One and Two or just It.
