Punch animation offset

I want my player to be able to walk and punch while walking. So I created a new layer and a new mask with only the upper part of the body. Now the problem is that the punch animation is offset... I tried to fix that through Unity itself tweaking the animation options and even tried rotate the animation in blender. But I have 0 knowledge on how to do it so anything worked and I thought there might be an easier way to do it that I just don't know... Also say that the animations and characters I use are from Mixamo
