How to transfer bone rotation (ie forearm rotation with hand) from Metahuman Rig to another?

I transferred a Metahuman rig to my own asset and transfered the skin weight as well but when I rotate the hand bone, the 2 forearm twist bones don’t rotate alongside with it. I can rotate them individually and they deform the mesh correctly. In comparison to the original Metahuman BodyMesh, it’s functioning as it should by rotating the 3 bones together. Am I missing something?
