AimOffset BUG!

Hi everybody!
I decided to use aimOffset in my project but I’m having a little problem.
So as you can see in the video my AimOffset is set correctly, with “additive settings” on “idle animation” (even all the animations are set with idle as base pose).
Then in my animator I’m blending throught locomotion blendspace and aimOffset.
AimOffset is layered per bone with locomotion (without doing it, it give me other bugs).

The blend I do before final pose is for “equip and reload pistol” animations.
When I enter play mode, if I’m in Idle I can perfectly use the aimOffset, but if I start moving, that what happen:

Thank you for your help!
