Vertex groups not following bones of G8F in blender

Logtr0101

Hey guys. I recently brought my Genesis 8 Female to blender using the Daz to Blender bridge. I was happy with the results until I tried to pose the figure. It seems the vertex maps for the "upper jaw" and center forehead are not parented correctly so when I rotate the head, they do not follow (I believe this is the root of the issue). I feel like I've looked at dozens of solutions online but I haven't been able to find something that works. I have no idea how to simply tell those vertex groups to follow the head's movement. Please help if you can.
