Geo Zone not working consistently

I have 3 Geo Zones set up

California (for tax)
United States
International (everywhere other than US)


the US and International zones are set up for Payments. We only accept wire transfers from international customers and we accept credit card and Google checkout from domestic customers.

so Credit card and wire transfer works fine. but for google checkout even though I have the zone set the same way as credit card, it does not show up.

Any one know why it would do this?
