Cannot change Use Custom Mode or Swap Root Bone properties on Movie Scene Skeletal Animation Params

Two properties on the animation params are not exposed to BP

1. Access a skeletal animation section from a level sequence in BP (e.g. Get Selected Sections > Cast to Movie Scene Skeletal Animation Section)
2. Get the Section's Params struct
3. Break the struct and expand to see all its properties

RESULT

The Use Custom Mode and Swap Root Bone properties will not be there.
