How to make coupon not include shipping cost

Dear Support,

I am using AwoCoupon 2.4.8. After setting a percentage of a coupon, the discount also includes shipping cost. For example, I set 5% for the coupon, and if a purchase is $100, shipping cost is $10, the total discount should be $5, but now it is (100+10)*0.05=$5.5

Can you please advise how to set it so the discount percentage does not account for the shipping cost? Thank you very much.

Hello,

I do not see how that is possible.  Can you send me a private message with temp admin access to have a look?
