Anchor points is moving when i create bones

[0absolut]

Hello guys,
First of all, sorry for my english

I have an issue when i creating bones with puppet pins. For example, when i create an arm, in my basic position at shoulder i have anchor point in a place but after i rotate the arm, my anchor point is moving a little bit.

I put some pictures with arm in basic position and after i rotate the arm.

Photo with horizontal hands is in basic position
Photo with vertical hands is after rotation (anchor point had another position in particular at the real left hand)

I mention that how i create this: one arm is one pice, i put 3 puppet pins, than i create bones, i create a controller at palm position after that i select all this four "pins" and i create IK(2 layer ik & goal)

How can i fix anchor point position and why is happened this?
Thank you and i hope you understand the problem I have.

I think this is an issue with the puppet tool of After Effects, not bones.

BTW, what is this version of Duik?

Duik version 15.52

I think it's time to update

Display the mesh of the puppet tool and see if you have enough triangles, this is usually the cause of this kind of issues.

I've updated it - same problem

At puppet tool: mesh is check, expansion: 0, triangles: 400
What's the right settings or how it's influences rigging this settings?
