Am I missing something here?

I just started a fitday journal and in adding eggs to my daily food list I noticed that the nutrition label says that one extra large egg has 1.59 grams of carbohydrate. But, when I look at the Atkins carb counter it says that 1 egg has only .6 carbs. What's up with that? Who's correct and are there many such descrepencies between the two?
