Ragdoll Mesh Deform

I'm just starting with Unity 3D. The problem I have, basically when the character jumps from the X height and when approaches the ground, enters in Ragdoll mode but the different parts of body deform, specifically the head. I'm using the Ragdoll Creator of Unity. I've tried to enable projection from joint character options or deegres projection angle but still deform.

My code:

Code (CSharp):

1. private void RagdollMode(bool state)
2. {
3.     Component[] coliders;
4.     Component[] rigidbodies;
5.     Component[] charJoints;
6.  
7.     this.anim.enabled = !state;
8.     this.capColider.enabled = !state;
9.     this.rbody.isKinematic = state;
10.  
11.     coliders = this.body.GetComponentsInChildren(typeof(Collider));
12.  
13.     for (int i = 1; i < coliders.Length; i++)
14.     {
15.         (coliders[i] as Collider).enabled = state;
16.     }
17.  
18.     rigidbodies = this.body.GetComponentsInChildren(typeof(Rigidbody));
19.  
20.     for (int i = 1; i < rigidbodies.Length; i++)
21.     {
22.         (rigidbodies[i] as Rigidbody).isKinematic = !state;
23.     }
24.  
25.     charJoints = this.body.GetComponentsInChildren(typeof(CharacterJoint));
26.  
27.     for (int i = 1; i < charJoints.Length; i++)
28.     {
29.         (charJoints[i] as CharacterJoint).enableProjection = state;
30.  
31.     }
32. }

Any idea of why it is deformed and how it can be solved, please ?

when I use blender to build a rig, mesh deforms. but in term of mixamo rig, it does not happen
