After rearming 234 the weapon selection reads RTO but if you fire secondary it drops a bomb. If you use the select secondary command (bkspc) it still reads RTO and then B50. To reproduce this error hold the brakes on the rwy and fire rato. Then drop ord and taxi to rearm. After rearming the selection window will read RTO. Firing secondary releases a bomb instead of firing rato and after the first bomb drops the window will then correctly read B50.
Load tested is with 1k (500kg) bombs and rato with no tail gun.
