Bad experience blocs website in Windows Edge browsers

I was testing my first build website in Windows Edge (Windows 10 version 1607 - running on Parallels 10 on my Mac) and it give me a very bad experience. The sticky Hero Navbar is jumping all over the screen when I scroll fast up and down the page. When I use the navbar on the other pages (which use the Top Global area), then there’s no problem. Is there a special adjustment I need to make for Windows Edge browsers to get a better experience?

I looked at a @Eldar template as well in Edge, and it has the same problem.
