X-Cart forums - Percentage Coupon Displaying Wrong?

We've had some modding done by a third party and then some modding ourselves to our coupons and the entire site. One of the mods is to get the absolute coupon code to apply to the entire cart including shipping rather than the sub total.

But now I'm trying to create a percentage coupon and the math is correct but the discount displayed is incorrect.

IE: $120 subtotal apply a 20% coupon the total is changed to $96 but it looks like $120-$20=$96 instead of $120-$24=$96.

Anyone have any ideas? The third party can't look at until the end of the month.
