Weapons Select Secondary problem

[Guano]

IN an M4 w/ rockets.  I have weapons select secondary, from global, mapped to a button on my joystick, but when I use it it only displays ap and smk..no he or rockets.  But backspace on the keyboard works fine, but is awkward.  Any explanation for this?

Thanks

Maybe your getting a double push on each press of the button on the stick. Some sticks have a rapid setting, maybe something to look at.
