This is a problem that can occur if an object is nonuniform scaled and it’s local transforms are not reset. If for example if you scale up the hip bone and not reset the scale in the bone tools then it’s rotation rate will be twice or half the rate of the parent bone.
To see if this is the case in 3ds Max select a bone in a progressive order and make sure it’s relative scale is set to 100%. If it’s scale is more or less than 100% strange things will happen.
Must know things about 3ds Max.
If you scale anything in 3ds Max using the scale tool it only changes the relative scale of the object and not the local scale that seems Unreal 4 uses . This can create problems when trying to move something or when using a physics based solution so be sure to xform rest mesh objects or use the bone tools resets for bones. Be sure to unlink the bone you are resetting or the reset will migrate up the chain.
