Hello,
My discount coupons are working fine as expected and users are availing the discount, unfortunately, it is not stored in the orders_total table and that is a lot of problem, here it is in detail:

On our store, fast and easy checkout is implemented and active, at the following page:

index.php?main_page=checkout&fecaction=null

When discount coupon is applied, it works and this is what I see:

Sub-Total: 1,750.00
Zones Table Rate (1 x 3,400.00gms): 2,050.00
Discount Coupon: dc2013 : -437.50
Total: 3,362.50


Correct value after discount is passed to the payment gateway. But when it comes back on the page:
index.php?main_page=checkout_process
The Discount Coupon is missing and therefore not stored in the orders_total table
Array
(
[0] => Array
(
[code] => ot_subtotal
[title] => Sub-Total:
[text] => 1,750.00
[value] => 1750
[sort_order] => 100
)

[1] => Array
(
[code] => ot_shipping
[title] => Zones Table Rate (1 x 3,400.00gms):
[text] => 2,050.00
[value] => 2050
[sort_order] => 200
)

[2] => Array
(
[code] => ot_total
[title] => Total:
[text] => 3,800.00
[value] => 3800
[sort_order] => 999
)

)


I tried with COD also instead of payment gateway, unfortunately no luck.

I'll appreciate your help, thanks.
