Yes you are right. I had something set wrong.
However AUTO mode works weird, bombs are not releasing most of times and you get the no authorized vertical lines on HUD when you hold pickle.
Most of the time, you have to time the release cue to drop bombs. First release will drop minus 1 bomb of the quantity selected and for the last bombs of each pylon only half of them are released (ex. 4 bombs left, each in one pylon, quantity set to 4, only two are released.)
