Incorrect total when coupon is used

[missjane]

When a customer uses a 10% off coupon, the totals are right for the customer and for the invoice when it is in "processing" status as shown:

 

 

 

Sub-Total: $290.93

Shipping: $0.00

Discount Coupons:wholesale10: $29.09

Total: $261.84

 

After I change the status on the order to "shipped" (or delivered), it shows this in my orders:

 

 

Sub-Total: $290.93

Shipping: $0.00

Discount Coupons:wholesale10: $29.09

Total: $320.02

 

 

So, I have a correct invoice for the customer and for my records (I print 2), but why is it showing incorrectly (actually it's ADDING in the discount amount) in the orders section of admin?

 

Thanks for any insight....
