Sticky div not working on higher screen sizes than 1280 pixels


Im working with a sticky div, it seems to work perfectly on 1280pixels - the base breakpoint for desktop. But whenever I go to 1440px or higher the sticky div doesnt work anymore. I can’t seem to figure out why.

I posted the read-only to my website, hopefully anyone can figure out whats the problem, I feel like its probally something simple but I just can’t seem to figure it out.
