Aim Offsets Transition by blend pose


hey everyone I am trying to have different aim offsets for different animation state like unarmed and rifle, I was able to come up with this solution but when switiching fro unarmed to rifle, the character sinks its feet in the ground for few mili second, i tried findind its solution in ChatGpt it says make sure you are using same base pose for both aim offsets and I tried that didnt work, need your help. Thanks in advance
