Error when a coupon is applied

Hi Team!

I’ve noticed if a client has a 50€ order, then applies a 10% promo code and then passes the order, he will get points based on the 50€ order and not final 45€ he paid.

I want my clients to earn or redeem points using the final amount, after promo code is applied because they should get points on what they spend.

Can you tell me how to fix this?

Thank you
