Hi @munch1
Yes. That is correct and not a bug. As you know, when you click from any menu item which has an anchor (like #design), it will scroll to a relevant section on the homepage.
For example, you have the menu: localhost/mysite/residential-services/#design, and when clicking on this menu, it will scroll to Design section, however, if you don’t have this section on the homepage, it won’t work.
This happens on the homepage only, so that is why you can right click and open it from any other page.
Hope it helps!
