Librarie only show a single movie

You can use quotes to allow for spaces in the movie names.

Code:

chris@rat-trap:/media/library/Movies$ ll The\ Super\ Mario\ Bros.\ Movie\ \(2023\)/

But it looks like it can see the movies if ffprobe scanned them.

Have you tried a "replace all metadata" scan type?

If you go to the metadata editor does it show your movies there?
