Payment - FirstData EMEA Connect

Hi All

I have recently upgraded 2.0 to 2.1.0.1 and I am testing the order and payment using FirstData test API.

I am using OpenCart build-in FirstData EMEA Connect API.

1. When I add a product in cart and checkout, at payment page, I put wrong card security-code.
->Page is redirected to : route=checkout/checkout, and status message bar displays : "INVALID TXN"
->A order confirmation is sent out via email.
->Order history shows "Processed" order status.

Ideally should have failed or declined status and order confirmation email should not have been sent.

Please can some one help me whats wrong here?
