How to make navigation title different from page title

My client needs only static pages, so I created a menu of pages, and then in settings designated that a “static page” be the landing page. The page I want folks to land on should read “Home” in the nav bar, so in the menu area I assigned the word “Home” as navigation label. It’s my understanding that this should replace the default nav. label which is the title of the page – but it’s not; it’s still showing up as the page title. (Also, when I select the static landing page in settings/reading, it also lists the page by it’s page title, not the navigation label (“home”) I assigned.)

The theme I’m using is Book Lite. Help here would be enormously appreciated. This seems like it should be an easy fix!
