Refund products including coupon discount

[ylli]

Hello,

 

I have a problem with product refund. When i have an order that has been applied a coupon discount exp 10%. when i do the refund of one of the products of the order the product price is counted as the original price not the price with 10% discount so i am giving customers more money that they paid for the product. I know that the discount is applied to the total but when i refund i do that only for one product. is there any way to fix this ?

 

Thank you
