National Discount question

When I put in for a $25.00 coupon through National, and using the KLM code, why does the coupon show as below with a minus 25.00 and then adding back $14.74?

Base Rate - Midsize (USD)
(1) Time & Distance ($212.41/Rental) $212.41
Discount Coupon Accepted ($25.00)
Discount Coupon Accepted $14.74
Contract ID Flying Blue/air France Klm
