In cruise mode plane keeps climbing. Plane 3.8.3


I need help trying to understand if this is a hardware issue or some kind of glitch during boot up.

Flight 0039 every time the plane is set to cruise raises throttle and keeps climbing even when setting elevator down the plane kept climbing. FBWA was level. Cruise height is set to 30 meters.

Flight 0040 Cruise works as intended. No changes to the plane or settings, just unplugged the battery and plugged back the same battery,

Thank you
