Arcade Basic – dropdown menu problem

I have created a dropdown menu in the Arcade basic nav bar.
Let’s say I have a page called PAGE 1 in the nav bar, and under that I have Subpages 1, 2, 3 etc.
The problem is, when I click “PAGE 1”, it will not show that page, but the Subpages are clickable and will show.
The strange thing is, when I’m in “customize”-view, then the PAGE 1 is clickable and the page shows. But as soon as I go back to “normal” view, the problem comes back.
