Sale is not shown at Payment Details or Payment Breakdown

I noticed that someone had gotten an item from my store that they had gotten a free code for from me, but in the payment breakdown it does not show what code it is, nor that the code is the thing that made the price free…

this is also an issue with other codes, I have another code that is not 100% off, therefore it makes it hard to figure out which code they used and how much money was taken off of my order due to the discount code…

Screenshot for the first scenario.
