Additive Layer not updating Virtual Bone Position?

i wanted to move the hands more forward/ far away from the face
this is the ALS Anim sequence.
if i add all the bones to the “Additive Layer Track”
visually its okey.

However the Virtual bones are no longer in the correct position, i manually move them…
and my weapon is still attached to the old position of the Virtual Bone:
RHS_ik_hand_gun

Default Location

after the additive layers:

how it looks when attaching the weapon:

anyone ?
is there a different way of accomplishing this ?

im still stuck on this
