Quest2 controller operation issue in Unity

HI,

I have a strange problem with the Quest2 controller operation.

The question is  that I  tested "CustomHand" sample of Oculus Integration SDK. 

The thumb and index finger cannot be controlled, only the middle finger to the little finger can be controlled.

I have test another Oculus Sample "CustomControllers" ,All buttons work.

Does anyone know what the problem is?

 

Unity version :2021.2.13.f2

Oculus integration SDK : V38
