When applying 100% discount on shipping, the correct discount is applied but on the order details the percentage is only shown as 50%.

1. Create new discount with target set to Apply to Shipment, add a coupon code, use percentage, set max discount to $50, and discount percent to 100%.
2. Add items to cart and proceed to checkout, apply coupon code
3. Review discount on Order Summary
4. Complete checkout and click button to Go To Order Details

Expected:
Discount shows as 100%

Actual
Discount shows as 50%
