Menu on pages – outside the landing page

Hi,

I use the enfold-theme to create a landing-page with most of information on.
The menu in the header works fine and if you click an item of it, it automatically scrolls down to the specific area on that landing page.

But if I add an extra / separate page on the website, this page’s menu isn’t working anymore because it refers to a specific area of the home page (landing page).

How can I handle this best?

FYI:
—-
When I go to settings: “Menu’s”, go to the “main-menu” and click a menu item like this, I see:

* Menu-item is an “adjusted link” (to scroll down to specific area on home-page)
* URL = #expertises
* Menu Style = default style
* Use as mega menu = unchecked.

Kind regards.
Caroline.
