Shipping Settings

I am having some issues getting my shipping settings to work. I have turned off all countries but the US for now, but I cannot get the shipping costs to come out properly.

Here's what I have right now:

More than $ 0 Rate Value: 6.99

More than $ 20 Rate Value: 7.99

My cart subtotal is $46, but it is showing my shipping cost as $22.99. All other shipping methods have been disabled as well. Any help would be greatly appreciated. Thanks.
