Hello, i have a big problem, I have an online store and I want to deliver by province and by weight, each province will have a cost depending on the weight, I have created 4 zones, each of the zones belongs to several provinces, but when I select the country that is Spain, the system only allows me to assign one of the 4 zones that I have created, and the other 3 zones do not allow me to select Spain as a country, a single country can only appear to be associated with a single zone. If I am wrong please I need your help. Regards. Alberto.
