My products have weight and dimension information. I have chosen Priority, Regional Box A, and Regional Box B (among others) as choices for shipping through the plugin. In the shipping calculator that the customer sees in the cart, there is only one option for Priority, not options for Regional A or Regional B, too. Even when I disable the general “Priority” shipping method and only allow Regional A and Regional B boxes, they do not come up as options. Can you help me understand why this might be? Thanks!
