Anyone else have this problem with Prime Video?

I was watching Beetlejuice Beetlejuice on Prime Video (through the Max subscription) and I noticed that it was rated R even though I know it's really rated PG-13. This is not the only time this has happened either this has also happened two other times. The other times include Batman: Caped Crusader rated 18+ when it's really TV-14 and The Dark Knight rated PG when it's really PG-13. In inclusion, I would like to know if anyone else has this issue.
