Preferred Angles Don't Work on Manny Thigh

1. Open Pretzel Museum project
2. Create an IK Rig from SKM_Manny
3. Add FBIK solver
4. Add Goals on ball_l and ball_r
5. Set Chain depth of goal to 3
6. Add FBIK Bone Settings to left and right thigh bones
7. Add Preferred Angles 0,0,40
8. Remove all iterations from the solver
9. Move both foot goals upwards

Expected result:
Preferred Angles blend in and thighs rotate

Actual result:

Only the left thigh preferred angle works.
