Compass calibration not complete

I calibrated the compass using QGC.

However, when I restart my pixhawk, I will be asked to recalibrate Compass.

I don’t know the solution because no error is displayed.

Please tell me the solution to complete the calibration of Pixhawk.

My firmware is the latest version of px4_fmu-v3 stable.

Thank you.

The firmware version has been reverted to v1.9.0.

Compass calibration was successful.

My pixhawk1 is made by Radio Link.

There may be something wrong with the latest firmware and this pixhawk compass.
