*sigh* I see now what happened. I thought I had set the tax zone for all products, but I have too many products to select them all at once so it was only applied to some of them. The product in my cart while I was testing just happens to be one that doesn't have it applied, and I didn't realize it because it just isn't obvious when a tax is selected if you only have one tax rate showing.

Thank you for your help.
