Part of the mesh is moving in opposite directions to the bendy bones.
Only 2 vertex groups here so it is not affected by any other group that I can tell.
Any Ideas? Maybe Something in the vertex’s properties? Thanks!

It’s not moving them. It’s rotating them and scaling them. As far as I can see, it’s behaving exactly like it ought. Reduce your bendy bone segment count and it will make sense; then, as you increment the count by 1 each time, it will continue to make sense.
Should be said that most of your weights are doing nothing, because most of your vertices are weighted to only a single bone, so the color really doesn’t mean anything. Weights are relative, so if a vert is weighted 0.1 but to only a single bone, it’s the same as being weighted 1.0 (or being weighted 0.01.)
