Accel issue

Hello. So far I have had an issue where my Accel values reset to 1. I start up as ususual and can see the hub off set In Mission planner. I then look and my accel values have reset to “1”. I load new values and all is good
I am on 3.1. Any ideas as to what is going on?

I think I found my problem, I was doing a “preflight calibration” in MP
that re-levels the plane I believe which is not good.
