Also these interviews are not done live so how would Dave not notice such a "glitch" before uploading?

Yep, that's the impossible part.

The only possible way this could happen is if praying medic had a glimpse of X22 on his side during the interview and then released the capture (not sure why he would do that), but of course that is not the case here since it has all the framing added, which is either added in editing or maybe during the capture in real time(to save on editing time later), but it would still only show on x22's side
