I'm little bit confused. What you mean is that HOME menu button is not focused?
If so, the navigation menu bar is focused when it is clicked, not depend on current page.
Becuase user access the page after login,not via menu button, Home menu button is not focused.
So if you want to set focus on HOME button when entering Default Home page after login, I recomment to use HTML/Javascript Snippet from marketplace.
Simply write a javascript code that give a focus status on HOME menu button.
