I meant that when the locked target was in the place where the altimeter was displayed (for example), this indication was not displayed so as not to overlap on the target plane. I saw a similar situation on HUD A-10C while aiming from a cannon to a ground target, it had priority over FPM (the crosshair symbol is always on top). There is no such thing at all in the F / A-18C module and sometimes it actually disturbed aiming - especially in VR.
