Issue with scroll animation

Hi All,

I’ve encountered an issue with the scroll animation on the “About Us” page on the current site that I am working on.

“Header 7” is supposed to stay next to the “About Section” as you scroll down the page, but I can’t seem to make the items line up.

Can anyone point out a flaw in the way that I have this set up?
