Mobile Menu has no content (I have read the FAQ On mobile menu)

When I click the mobile hamburger, the mobile menu shows no content:

I can see the maxmega menu javascript file has been enqued:

<script type='text/javascript' src='https://kingsoncapital.com/wp-content/plugins/megamenu/js/maxmegamenu.js?ver=2.7.4'></script>

When one clicks the hamburger I can see this element toggles from:

<div class="mobile_nav closed">

to

<div class="mobile_nav opened">

However in the element inspector I can see there is no content within the element.

From reading the documentation, it appears the mobile menu should have the same content as the desktop menu.

I have **not** selected any items to be hidden from the mobile menu. I can’t see any JavaScript errors that would be block the menu.

Should the <div class="mobile_nav opened"> not contain menu data? If yes, where does it come from?

Thank you
