Unable to get the "Original Membership Form" to work

I have been racking my brain for hours and I cannot seem to get the "Original Membership Form" option to work.

I have gone to the following setting: Membership/Options/Membership Pages tab

In the Registration Page section I have selected the Default "Register" page. I then go to my site, click the "Register" link I have set up. I see the two subscription options and click the first one. However, I am not taken to a registration form. Instead I am taken to a page that says "Create account" but there is no registration fields. I stitch to the "Popup Registration Form" and the registration field appear. I am baffled. People can check it out at:

I have attached screenshots of what I am seeing. Can someone please help? I am at a loss.
