Hello

Procedure:

I'll make some products with hikashop, then I create some characteristics and assign this characteristics to one off my products and put it different prices to each variants(Characteristics)

When I list the product with variants, in the product view, it show me the price off the variant, that it's correct

BUT

When I'll change the variant in the product view, the price don't refresh and I'll see the price off the default variant
