How to solve my problem with Avatar Mask in Unity?

Question

Unity

When using the Avatar mask (to control the top and bottom of the character separately):
Upper Avatar - (name: UpAvatarMask):


Lower Avatar - (name: DownAvatarMask):


If I put two Avatars on 2 layers in Animator:
1)
2)

Then my character shrinks:


And if the Avatar is thrown only one layer. Then the animation will be the one on which the Avatar is attached.

Who has any ideas for this?

Extras:
-Model and animation made in Blender.
-All Clips are listed.
