Sorry but I canīt duplicate that.
Took my Ar to 4000ft, then went to calibration. After calibration I got exactly the same view you posted, but only because I had still RTO selected. After selecting my bombs, I went through calibration again and everything was fine then.
It does not make a difference if u have actually the RTOs used or not, because selection doesnīt change automatically after usage, you have always to manually select bombs before calibration.
