Shannon character armature issue

[Ramon5F98]

How to replicate:

Select Shannon from the characters list https://www.mixamo.com/#/?page=2&type=Character

Attach any animation to channel

Look at his hands during the animation. Ring is the ony finger that bends (and deforms most of the time), the other fingers don't.

The problem persists after importing into Unity or Blender.

confirmed... the error is in the model itself
