I am trying to enable USPS and free shipping just for international orders. I have created an international zone that includes all international countries we ship to. I have specified the same zone in the USPS ship zone dropdown (as well as flatrate option dropdown).

However, the USPS shipping and FLATRATE OPTION shipping modules show up as orange and not green, indicating something is not working. When I do a test order, these two shipping methods never show up.

If I disable to ship zon in these 2 modules, they turn green and become enabled (although for all zones).

Is this a bug with 1.3.8? Or do I have to do something to correct this?

Please advice.
