Physical Virtual Alignment Program After taking off and then retaking on the headset

I encountered a virtual-physics alignment problem, but in my situation, when I take off the headset for a while and try to put it on in another pose (still inside the boundary), all the virtual calibrated objects misaligned with the physical ones. As I have already set to the "Stage" mode, all the physical positions should be on the same relative to the same origin. Therefore, I guess the origin still changed after the headset lost focus. 

Does anyone have some ideas about that? Thanks!
