Why are all my tax areas being displayed in the shopping cart?

[fizzlepop]

I have two tax areas defined:

Tax Area: Washington
Tax Area: US States Not Taxed

The Washington Tax Area is mapped to the Zone "Washington"
The "US States Not Taxed" tax area is mapped to the other 49 US State Zones.

I created a Tax Rate "WA TAX 9.5%", and set the tax rate to 9.5 and the Tax Area to "Washington" and Priority 1
I created a Tax Rate "Outside WA State" and set the tax rate to 0 and the Tax Area to "US States Not Taxed" and Priority 1

(I do not want orders from outside WA to be taxed)

Now, everything as far as tax calculation is correct. WA residents are charged 9.5% and residents outside of WA are not charged tax. However, in the shopping cart, several tax areas and zone are show in the cart (see image).. How can this be remedied?

Hello. I just looked in the database and noticed all these entries in my tax_rates table. The odd thing is that the konakart admin utility only displays 2 of these:

After deleting the "phantom" rows from the table, they stopped being displayed in the cart.

The real mystery is why these rows did not show up in the Admin application?
