controller redirects to same page and creates a page inside a page

Hi!
I'm having a strange issue. My page is essentially several forms on the same page but when one form is completed and I do everything I need on the backend, I use redirect(base_url('dashboard')) but it creates the same page on top of the page that was already there. So If I scroll down, I can see the same page (although broken because of javascript stuff) Speed Test Scrabble Word Finder Solitaire


Has anyone dealt with this issue? I've never done a single page site before. I appreciate any feedback! let me know if you want to see the code.
