If you are trying to ask anything else then please provide some relevant screenshots of the specific area
to check it myself and help you out accordingly.
I saw the screenshots you attached; this is how the demo import works; only the available menus under Appearance >> Menus are displayed when you select the demo layouts.
If you want to create the exact one then you need to create on for yourself from Appearance >> Menus.
Then you need to set the menu as the main navigation.
