Coco Hydro Instant Coconut Water

I bought this package of Coco Hydro Instant Coconut Water Electrolyte Drink in the original flavor today, and the back of it says:
Serving Size Custom Food 22g
Calories 5
....
Sodium 7mg
blah blah blah

But when I looked on MFP to add it to my diary, it says the serving size is 11g and the Sodium is 70mg.

I am confused.

I also went to the company's website to check, & their nutritional information says the same thing, but when they list the ingredients, they also list the natural flavorings & colorings used in the flavored powders. So I'm wondering if their nutritional information on their website is for the flavored powders, not the original.

Can anyone explain to me why these sets of information are so different?
Does it have something to do with the "Serving Size Custom Food" part? I don't even understand what that means.
