Sticky navbar not working on live site

Hi eveyone,

On my homepage for tablet and mobile devices I have a notificationbar above the navbar. I have positioned the notificationbar to static and the navbar to sticky, because I don’t want the notificationbar to scroll down the whole page, but the navbar should.

In the designer everything works perfectly, but for some reason the navbar is not sticky on the live site. I don’t understand what goes wrong. Can someone help me with this issue?
