Enfold single page site menu "current-menu-item" bugged

Hello dear enfold support,

I encountered a problem with enfold concerning single one pager sections. I have a complete site with only sections and the enfold slider. But the enfold menu marker for the current section is bugged. IE: there are 5 different sections, that are also linked in the menu with anchors. But the page doesn’t highlight the current item. It behaves strange and marks the second menu item as active with every second scroll down (mouseweel and arrow keys).

I found your tech demos:

And both are able to handle the highlighting of the current section item perfectly. Only my current page has problems with it

Best regards

Frederik
