If I select /Alternate Ship To Address/ and select the address from the /Ship to Addresses List/ that should be set. Unfortunately. if I run a rate quote for shipping it will change the setting to Custom. This is a problem as it will not find the related address and collect account number in Dynamic ship. If it does not find the account number, it defaults to prepaid and billed which is incorrect. The software seems to want to run the ship to address as Custom. Is this a default.... why?
