I can chose different languages but can't disable them. Am I missing something or is has this been removed?
Arrow up to 'None' and press OK.
Not getting none. May have something to do with the video I was watching I will check some others.

If there's an actual sub file or track to manipulate - you should be able to manipulate it.
