Animation not working on the limbs just in the Control Rig

Hi, I did an animation outside Unreal Engine, that works in engine right, but after I added into the sequencer when animating in the control Rig, limbs doesn’t move, it looks like it could be the IK but when I switch to the FK using “arm_l_fk_ik_switch” the animation is still not working on the limbs, any idea?

If you did the IK control set and get bone, maybe swap the two around. I had simmular problems with my rig but I could not constraint rotation to them.
