Failsafe plane in calibration

Hy, I have a problem with the calibration of the plane mode in mission planner.

My problem is that when I calibrate the pixhawk with the mission planner, when I finish it and try to arm the plane, the light of the pixhawk continue being yellow and it appears the failsafe.

I try with other programs like Qground but it doesn’t fix the problem. could someone help me?
