A quick hack if you have no alternative handy is to throw in a slice of American cheese to counter the additives.
I've noticed that better quality grated cheese tends to behave better. E.g. Tillamook grated cheese melts nicely for me.

I go through a lot of bricks of Tillamook's Colby Jack.
edit: they might have begun adding gums. I have to buy Jeni's or Van Leeuwen. Ought to just make my own with how little I eat anyway.
