Home page Section

Hi,

On my Front page, my homepage section is duplicated. Even though on the Homepage settings on customize, it is set to section one only. What can I do to stop this.

Also I have a login for my site, and I want visitors to get to my front page only after logging in. However I have to set the register page as my front page, which messed up my parallax home page. How can I make the parallaxing homepage be after my register front page?
