The settings you have applied – according to the shortcode given – will only list the root page (“About Us”) if that root page is the current page.
I hesitate to suggest this, but …
You have set the text “About Us” as the title of the widget : Are you sure that you’re not getting confused about what is the title of the widget and what is the content of the widget?
For example, if you were to (temporarily!) change the title of the widget to, say, “Something Else”, and then to navigate to one of the sub-pages, do you then see any mention of “About Us”?
