Payment Manager

Hello,
I have successfully setup and integrated GD into my existing website. Just 3 minor issues to iron out.

1) on the check out page it seems as though the old payment methods are still showing below the the main payment options. This is ONLY happening when i testing out the scenario when a user might go through the registration process, proceeds to the checkout page , then navigates away from the check out page. Then the user goes into invoice list , and clicks “Pay this invoice” then the check out page loads and this happens. I only have Stripe enabled, and have tested stripe out completely and it works. Right now i just have a temporary solution by using css to display:none on that part. screenshot: https://snag.gy/cCIli3.jpg

2) After an existing listing is edited by a user, the site redirects to the screenshot below, the “Sorry, Trouble receiving payment receipt” is a confusing message it implies something went wrong, and i need to change it to something else. Can you tell me where to change this?

3) Similar i need to change the message that is displayed on the listing preview page. See screenshot. I need to reword the circled text. Screenshot: https://snag.gy/1eJMI3.jpg
