Multiple addresses checkout setting wrong shipping rate in the overview (review my order) page. In this particular case I am sending 3 items to one address and 1 item to another address.
this image shows my 3 items shipping to 1 US address. I previously selected the $15.00 flat rate shipping. The total amount is correct but the shipping amount displayed is wrong. It should be $15.00
Is this a known magento bug? am I setting something wrong?
