Gift Certificates - Duplicate Orders being Created

[ezboutiqueweb]

Hi everyone,
I'm pulling my hair out on this one... I've searched the forums and saw only one other person with this issue but no response or resolution to the problem.

I've set up a site for a client. Everything seems to be working fine. She has set up gift certificates for purchase on her site. When a customer goes into the store and purchases a gift certificate, TWO redemption codes show up on the back end. This is happening every time we test it - duplicates every time.

For now, I have set up the GC Queue so that she can release only one, but it seems to me there is something wrong, and I have no idea what is causing the cart to create two GC's/redemption codes per order. We are able to redeem both codes, so obviously this would cause a problem if the customers received a 2for1!

Any ideas/suggestions? I don't generally get too involved with gift certificates so I have no idea where to start looking for a problem. Thanks for any help you can provide. Screenshot is attached.
