Gift Certificate Charge Shipping

After installing and setting up the WooCommerce Gift Card, I tried using it to check for any problems. When it came time to check out, there was a shipping charge related (which is odd, since none of the shipping information was set for this product page). How do I remove the shipping? I am really looking forward to adding this to our site.

Thanks a bunch!
