Problem with the Napalm/ice/electric gun

[candymancan]

Ok So im a the level where your at Ryans offices, and my flamethrower weapon is outa ammo as i start the new map, so i go up to those clown machines and i buy some napalm. Now the spots for the ice and electric are gone i cant switch to them and i cant pick the ammo for it either, all i have now is the napalm choice and not the other 2. I walk up the Nitrogen ammo and i get not action button notice or anything, same with the electric stuff.

So now i have to finish the game with a gun thats all messed up... Whats going on here ??

Its also doing to me to the shotgun and the tommy gun, it seems if i only have at the time 1 set of ammo and switch to it i lose the option to pick up other ammo. WTF is going on here ?????
