I have just set up Amazon Payments as a payment method at my store, but have an important issue with it. I can successfully go through the payment process, i.e. I've done a couple of test orders and received order confirmation e-mails accordingly, but when I go into the back-office (Dashboard), I do not see any Payment and Shipping Details :

For what it's worth, I've only done test orders in Sandbox mode.
Is that an issue with Amazon Payments and what would be its solution, or is this the 'proper' way that Amazon Payments works, i.e. it has not been designed to return order information details back to OpenCart?
Thank you!
