I am having trouble with my zone rates and I have attached a copy of the shipping estimator below. The problem is that the total weight comes to 4.4lbs but the charged weight is 7.4lbs. This is adding a huge cost to my shipping to the US.

I dont understand why it is adding the extra 3lbs to the shipping weight.
