Problem with Gift Card Discount Not Covering Shipping Costs in Knowband Manager Gift Cards Module v2.0.5

[Marian3]

Hello,

I've installed the Knowband Manager gift cards module v2.0.5 from Knowband and I'm encountering an issue. When I use a gift card code, the discount is only applied to the product and doesn't take the shipping cost into account. For example, I have set up free shipping through the 'Carriers' tab for different carriers starting from various prices, but the minimum is from 100 PLN. Let's say a customer shops for 120 PLN and qualifies for free shipping, then uses a gift card worth 50 PLN. They should now pay 70 PLN, but end up paying 85 PLN because the gift card seems to reduce the order value, and as a result, we no longer qualify for free shipping.

Is there a way to configure it so that the gift card reduces the total value of the order including shipping?
