Marketing Deception

Since when does 2 cups = 8 ounces??? On the back of this bag of franken cheese, the serving size was 8 servings per 1 oz. That was accurate but where is the 2 cups they advertise?

I checked other brands to see if they all were claiming the same. All shredded cheeses claimed, 2 cups in the 8 oz bag. On the back of 1 popular brand, the serving size claimed, servings 5 per 1/4 cups. I'm a numbers girl and the math does not add up.
