PX4 main definitions loss

Hi everyone,

I’m using PX4 version 1.13.4 with cube orange.
After startup I happen to find my drone inoperable, doesn’t arm, and therefore doesn’t fly.
After connecting to QGround I find all definitions lost, including airframe, sensor calibration, magnetometer as can be seen in the following picture.

Does anyone know what can cause this reset to happen?
It looks like the firmware version remained OK but everything else needed calibration.

Thank you.

PS: I am using customized airframe that is selected from the known list by a parameter. After loading the parameters everything is OK part of the sensors tab.
