"cc" is what shows when you use the "Offline Credit Card" module which is enabled by default.
You apparently used that to type credit card numbers onto your checkout page ... but that's not how you use a credit card to pay with PayPal. You must choose PayPal if you want to pay by PayPal.
The Offline Credit Card module is only for merchants who have a swipe terminal in their office so they can type the card numbers in manually ... and even that is frowned upon from both a PCI security perspective as well as many terminal contract agreements. Without such a swipe terminal (real or virtual), there is NO WAY for you to process any orders you take with that module.
Click on the Offline Credit Card module, and click the Remove button.
Then do your payment afresh.
