This page isn’t rendered on the website, however it’s kept here to act as the organizational parent of the sub menus. The [unclickable] menu named “About Us” on the website is a custom link added in the appearance section with a # as a URL. Once the link was added with a # sign as the URL, if you delete the pound sign then that renders the About Us menu unclickable (however in order to add it in the first place you MUST designate a URL, hence the pound sign followed by the deletion of it).
