Mobile header links to front page, not home page

Pretty much what the title say. Up to the moment when “my-site.com” was the link of the front page (first page to appear) AND the home page altogether I had no problems. Now that I’ve elected a specific newly created page to appear first when typing “my-site.com” and another one to be the home page, the mobile header for my site keeps linking to “my-site.com”, which at moment shows the front page (a disclaimer page).
Where do I change the URL inside the mobile header?
