New to Illdy needs advice

A few questions regarding Illdy:

a) Problem with menu:
I did set up menu exactly as showed in this video from Colorlib: How to setup menu and sections in illdy WordPress theme - YouTube
So now there are new “buttons” to choose from on the top of the page. However, when clicking on these “buttons” on the new menu, I am not being forwarded to text that should be below on the front page. How to fix this?

b) Problem with background image:
I did set up background image in the “Jumbotron Section” and it works fine. But when I create another page, the new page automatically has some background image of a coffee cup. How do I set up my own background image in new pages?

Kind regards from askja.
