I have a site configured with 2 product types. For one of them I have the flat shipping rates applied. But I have the problem with flat rates and UPS shipping rates. When I try to checkout the item which only uses the flat rates, in the review page it shows zero shipping cost. When I try to checkout a cart with items which works with UPS and FLAT RATE, in the review it shows ok.
I have Ubercart 6.x-2.6 and the UC_Combine_Shipping downloaded today. What could be wrong? I haven't modify any CA (there is any condition to the shipping CA).
