ammo_*grenade_max cvar?

[drsp]

Does anyone know how to make these work?:
ammo_hegrenade_max
ammo_flashbang_max
ammo_smokegrenade_max

The server registers the new values, but noone can buy more than the default number of grenades.
All the other ammo_*_max cvars are working as they should.
I suspect that they are broken somehow, but i hope you guys can give me a tip/workaround for my little issue..
I do not want infinite grenades!

And yes, i did Google this
