Hi, I have a contact lens store. per box users can choose different amounts of boxes for left eye and right eye (up to 7) this and the other variables I created with the EPO plugin.

The price and the discount I have to show it as woocommerce does (attached screenshot), for this porduct I leave the product as simple in Woocommerce. But when making a purchase of a box for each eye the total adds 3 boxes instead of 2.

Is there any way I can fix this without always adding an additional box?
