Ghost Content! Hi.

Ghost Content! Hi. Everytime I create a new page, whether I use an Upfront template or not, it includes some legacy code from another page. If you view the page source on this page https://www.greatannualsavings.com/business-energy-procurement/ you'll notice near the bottom that there's code from the About Us page, namely the staff lightboxes. The About Us page did form a template but I've since edited the the template thinking it'll fix the problem but the problem still persists. Any ideas?
