Unable to remove a quantity discount when editing an order. I have this http://www.zen-cart.com/downloads.php?do=file&id=135 module installed. When you edit an order the quantity discount down in the total doesn't have a text box for the amount. It does have a text box for the title "quantity discount". But without the text box I can't adjust the amount. The discount also doesn't change if you remove any products. But that would be okay if I could adjust the amount of the discount or remove it. Thanks for your help.
