it was hard to sum on the title, basically what happens is that we set a special price to te lowest price option in a configurable product but it affected the next ones. For example, image we have an option that costs 5 and the next one costs 10, in the dropdown would look like +5 the second one. Now we set a promotion only to the 5 and set it to 3, now the second should cost 10 because the promo it's only for the other option, but it doesn't, it costs 8 because it assumes it's the promo 3 + 5 that is the difference from the original prices.
Don't know if it is understandable. Any solution to this issue? I can't find anything
Thanks, Best regards
