No redirect to top and footer pages

Hello,

I just activated the twenty twentyfive theme. All is well, it looks aesthetically pleasing. However, when I created the top bar and footer menu, and added the link to the designated pages. It does not redirect to the actual e.g. ‘about’ page. It redirects you to the home page again. Would you please be so kind to help me out on this matter? I am not sure what I am doing wrong here exactly.

The page I need help with: [log in to see the link]
