Step by Step.
1.Put any actor on scene.
2.Open "2d motion key editor"
3.On frame 10 click "Flip Hip", now we have a Flip Hip keyframe on 10.
4.On frame 20 move hip to any place (Motion>Transform).
5.CA create a keyframe on 10 and on 20, if I want to move the hips 0 to 20 it is not possible, it will stay until 10 and move from there.
6.Delete the 10 keyframe hip (Motion>Transform), the duplicate one.
7.Move the 20 hip keyframe to 30, CA create again a keyframe on 10.

Looks some kind of conflict between "Flip Hip" and Hip keyframes.
