Problems with sticky Navbar

Hey Webflow Community,

I just build my first clients site in webflow and I’m really impressed. (Also is my client totally in love with the editor :slight_smile: ).
But during my final quality check I mentioned a strange behaviour of the navbar. I defined it as sticky so it should always appear on the top of each site while scrolling. This works so far, but only on the main page there is a problem. After scrolling trough the second section the navbar just disappears as it would not be sticky. On all other sites it just works perfectly fine! Do you have any idea how to solve it? I already searched the forum and watched the corresponding webflow university videos but I don’t found a solution so far.

Thank you guys in advance for your support :slight_smile:

Here is my site Read-Only:
