Navbar and Footer Issue: Sections Not Found in Project

Hey team Having the same issue as Aurelien above. Comes up with a bunch of freaky looking code! I looked at the project on an incognito window so i was logged out and it showed the navbar and footer as sections the system couldn't find and highlighted them in red. Ref attached screenshots. Please let me know if I should do anything. My email if you need to contact me is: levi@revampdigital.co.nz
