Please help on registration form issue

at I have membership setup underway. However, the protected content function is the only thing barring access, so I set it to the registration page. The shortcode in that page pulls up a very….unsightly registration form. Nothing like in the pdf I downloaded. Also, I can’t figure out how people login. Like I said, the example is nothing like this. Please take a look and tell me this is not supposed to be what is there
