Shipping options not showing on product page, but shows in the checkout

Hi,

Thank you for this nice plugin. I have an issue though.

Seems like its not recognizing the address on the product page. When I enter an address and update, It does not show any available shipping methods, however if I go to the checkout and enter address details, it shows available shipping methods.

I hope you could help me. Thanks
