Rigify jaw master problem

Hi, i am facing a weird problem with the rigify wolf rig where the top gum comes down with the jaw and the bottom teeth stay up when i move the jaw_master bone to open the mouth. I have manually fixed the weight painting for the top and bottom teeth (i included the top and bottom gum respectively) and i also tried weight painting the jaw_master bone but since it has a weight of 0 everywhere per default that also didn’t make a change. I am at a loss which bone is pulling the gum down and why the bottom teeth don’t move with the jaw. Can anyone help?
