Humanoid Avatar mess up Animations

I have few animation that when i have my model on Humanoid and the Root Motion is off the rotations on Pelvis and Chest are gone.
My avatar configurations are correct. When i turn on root motion the animation works correctly but i don't wont the model to move from the root motion.

So when i have it on Generic it works perfectly. But i lose the mirror option and i can't use other humanoid animations if i want to.
I saw that others have the same issue but not any solution about that.

On this video i think she has the same exactly issue with me:

Also i don't have any Import Messages.
The animations are separate FBX files (made for this specific model) and Copy the Avatar from my base model that it's just a T-Pose animation.



What you say should i stay on generic and make the mirrored animation on the 3rd party animation program?
Or keep looking for a solution? Because i can't find anything else on this.
That's why the post...

 

Did you find a solution for this in Unity or end up using generic and mirroring animation in 3D app?
