Hi all. Google checkout has been working fine for us but I just tested it to confirm and no matter what I do GC says we sent them a bad cart? Here is the error given in the GC integration panel:

<?xml version="1.0" encoding="UTF-8"?>
<error xmlns="http://checkout.google.com/schema/2" serial-number="86dfe8a8-b07c-40fc-9c69-dc7d962bc7eb">
<error-message>Error parsing XML; message from parser is: Invalid value for body of allowed-areas in checkout-shopping-cart/checkout-flow-support/merchant-checkout-flow-support/shipping-methods/merchant-calculated-shipping/address-filters: Must be a U.S. 2-letter postal code or state name</error-message>
</error>

What is the problem here? The only thing I have changed lately is I customized the shipping zones a little... Any ideas?

ZC: 1.3.71
GC Module: v1.4Beta1
