I was creating a listing and setting up my shipping options. When I select tick all countries, it ticks all countries for all shipping options.

This happens for Calculated Shipping only, not Flat Rate Shipping.

I am on the ebid Canada site. I set up Domestic shipping for Canada, then I setup International shipping, first for USA only by a simple tick on USA with a USA shipping option. Then I add an International shipping again using the +, I tick all countries and all are selected for both shipping options I chose! My intent was to tick all countries on the second shipping option and untick USA.

If I repeat the same scenario above for Flat Rate shipping, it behaves the way I expected and only ticks all countries for the shipping option I wanted.
