Section doesn't stick on horizontal scrolling

Hi All,
I’m building a horizontal scroll website and having a problem with making some part of my design to stick to the left side of the screen.
while previewing the site in Webflow the sections stick correctly (with a small glitching) but after publishing they act completely different.
I would appreciate it if you can help figure out what the problem is and how to fix it? or if there a more proper way to design the site?

Thank you in advance
