Rotation of Turn Animation is doubled when root motion is applied in Unity

Hey guys. Is someone familiar with root motion in Unity? I’ve made a turn Animation in Maya and then exported it as an fbx, imported it into Unity and connected with the character. Animation looks fine in Unity. Now our Programmer tries to put Root Motion on the Animation. Problem: the rotation doubles. Original animation has 90 degree, with root motion 180 degree. Second problem: I have very poor knowledge about unity and the Programmer is not very familiar with the animation topic in Unity and in Maya. I’m not sure if I did something wrong in Maya in the first place. My root bone is at the hip position. It’s not at the 0/0 Position of the world but that shouldn’t be a problem. But my knowledge about Unity is nearly zero. I would be very thankful if someone could give me an advice.
