Credit Card Details Message always displayed

I have setup a PayPal Website Payment Pro account and have added the API, username and password to the opencart admin PayPal Website Payment Pro payment option. After I place an order on the site, I see in the Credit Card Details section "Please wait!" message. This message appears to display forever, never redirecting me to an invoice page.

But when I login into paypal I see the order was placed and I received email from the shoping cart site saying confirmed with the order details.

Why doesnt the shopping cart site redirect me the invoive page/confirmed page so the your know the order went through???
