That's the version they released as an "open" model. Their SD3 model behind an API works just fine, the released medium model has been basically been lobotomized to hell and back in the name of "safety", because apparently human anatomy is icky and nipples are the devil. Unfortunately, that sort of heavy handed model lobotomizing leads to nasty side effects that turn even innocent renders of people into Eldritch nightmares as the model has been forced to forget that a human doesn't have limbs growing out of random places.
