Set Master Pose Component - Wired Animation. Please Help!

Hi! I have a skeletal mesh rigged with mixamo. I want to use costumizable hair and clothes for my character. So i add a hair mesh to original skeleton and skinned it in 3DS max. The skeleton is the same with original model. All bones have same names, ierarchy and weight. But when i use “Set Master Pose Component”, hair animation looks wired. What i did wrong?





Here is the full skeleton ierarchy:
