Avatar Mask- Turning of Ground Mask prevents character rotation

Hey, i wanted to set up a Upperbody animation by using Avatar Masks.
But as soon as i turn of the ground mask, a very important part of the animation gets lost - the rotation to the front.
so normally the character punches to the front, but with the mask off he is punching to the side as you can see here:



is there any way to keep the rotation without turning on the ground mask?

cause this is how it looks like ingame:

you see, when i turn on the ground mask (between the feats, I dont know how its called). the Punch goes in the right direction (front) but also the legs are moving with the punch. if i turn of the ground mask, the punch goes in the wrong direction but the legs are correct. also the movement is not working anymore when i turn on the ground mask.
how can i make both working: the legs and the punch in the right direction?

here are some more pictures from my animator and animation settings:

Have you tried creating a mask from the actual skeleton, instead of the 1 you click on the body parts? In the full skeletal hierarchy, you have access to every bone, so you can pin point the bones you want to keep.

 

Sorry to bring this out of the grave but im getting this exact same issue, (tried the above solution and the same problem occurs)

 

Same here 2 years later! Does/did anyone find a solution to this issue?
