Hi,
I found the problem in the multi-shipping system in HikaShop.
I made some modification in order to right reprocess the weight/size/price for each shipping group and introduce a new element.
The new element display a message when a shipping group does not require shipping (but other shipping group need).
These modification affect several files in HikaShop, we planned to make a new HikaShop release during this month.
If you don't want to wait for the release, we can see to send you the list of the modifications.
regards,
