On the AH-1F helicopter, some of the pylon loadout presets are not valid and don't properly apply.
The "16x TOW" loadout attempts to put 4rnd TOW launchers on all pylons. However, only the two outboard pylons can carry TOWs, so the inboard hardpoints remain empty, leaving the total missile count at 8.
The "2x M247, 2x M255" loadout attempts to put 19rnd M255 rocket pods on the outboard pylons. However, the outboard pylons can only carry TOWs, so the outboard hardpoints remain empty, leaving only the M247 pods on the inboard pylons.
