SOLVED: Library shows with 3 folders not showing indivisual

[Efficient_Good_5784]

Library is using show and movie option (have also tried movies and same result)

Are you using the "mixed movies and shows" library type? This library type is not well supported.
I would recommend to stick to either shows or movies and to make collections if you need to merge the two.

My work around is copying those files to its own folder with media/home movies/familymovies/8mm Home DVD/season 01/home dvd movies S01E01.m4v
and setting the library to path media/home movies/familymovies

This is probably the issue. From what I read previously, you're adding the "show" name as "Season 01". With your "work around", you're linking the familymovies folder as the actual folder to use for the library. Then in there, you have an actual show name "8mm Home DVD" with it's own Season 01 inside of it.

I would suggest you look at the documentation and make sure your files are sorted as close as possible to how it's described:
