Replacing page and it just redirects to the old one

Built out a page that essentially functions as a landing page for a site I run, so it doesnt have the theme as the rest of the site. Tried just swapping out the slug lines in hopes it would keep most my links intact, but it just redirects to the old page regardless of what I do. If i input the URL directly it still just redirects to my old page (now under a different URL). Not sure what's going on here, any help would be greatly appreciated!
