We have a 5% discount applied for customers in the Staff group when the cart total exceeds ₹2000. The discount works correctly when the amount is above ₹2000. However, when we reduce the quantity in the shopping cart and the net total falls below ₹2000, the discount should be removed. Although the net total updates correctly, the grand total shown in the payment summary does not update and still shows the discounted amount. Please check and fix this issue so the grand total reflects the correct amount after quantity changes
