Fimo73 on "[Plugin: Sticky Menu (or Anything!) on Scroll] Sticky menu produces white space"

Hi,
the plugin is really great. There is just one thing I can't fix: my sticky menu in the Divi-Theme produces some white space on the element above. You can see it her: http://hilfe.raum73.de/
The white space is exactly as height as the menu. So I guess there is only some kind of padding-thing going on? I tried this on another dev-site:

#page-container { padding: 0 !important;
}

White space is gone, but now the static menu overlaps the element undeeath when you start scrolling. And scrolling becomes really bumpy at the beginning: See it here: http://digital.haz.de/wasserstadt/
An idea on that?
Thank you very much for helping me out

Resolved. With the help of Paul from https://yatesdesign.com
If anyone else should encounter the same problem:
In Divi-Theme there is a built-in sticky-function working (.et-fixed-header), which grabs its own CSS. If one Idea this class out, everything is fine.
Thx
