Warhead size plays a great part in reload times from a ammo supply vehicle. So in this case, warhead size 2 means usually cluster munitions, so the game calculates it by that figure of 2, but similar for non-cluster HE rockets, the warhead could be, say, 11, so reload times are much slower, even for a identical rocket-artillery piece, with differing warheads.

It´s a bug, don´t know if it can be fixed though. Make Uragans off-map, as they probably would be anyhow.

Don´t adjust the Warhead though, since you´ll get super-cluster munitions, annihilation everything in their path.

Maybe Uragan has 2 salvos of 8 rockets. So it could have one slot of 16 rockets, but now has 2 slots of 8 rockets, which is usually the case in-game concerning rapid-firing rocket artillery.
