DK helm appearance removes part of my head

As of writing this, the Undermine raid tier helmet “Cauldron Champion’s Crown” removes the entire lower half of my undead’s head. I know some appearances are meant to obscure the head/face area with mist effects, but this straight up leaves a visible hole that I can see through where the neck and head connect and my jaw is simply nonexistent (even though there is no such barbershop option for female undead). I really enjoy the look of this set but that spoils it for me a little bit so I hope it gets fixed. Thanks, Del
