PX4 (v1.10.1) Error : Home position is not updated automatically

In v1.10.1, home position is not updated automatically.
It is why geofence RTL mode can not be used.
When geofence RTL mode is set and Arm switch is on,
the error message is showed and Arm can not be set.
Please tell me the cause of the trouble.

It is because EKF2_AID_MASK is 2.
When EKF2_AID_MASK is 2, GPS is NOT used.
Therefore, home position is not set.

When EKF2_AID_MASK is set 3, home position is set automatically.
Thank you.
