Payment Frame

Hello,
I have seen the plugin screen shots and also the upload video and noticed that on the test site there is a frame around the area where customers register. This makes it look nicer.
But on my site, I have it without the frame. http://glpstylist.com/membership-levels/membership-checkout/?level=1

How can I change this?
