Scroll animation going off page triggering horizontal scroll bar

On the home page of this site I’ve tried following this tutorial for a horizontal movement on scroll

Within webflow’s preview mode it works great. But once I publish a the link and open it in the browser, the animation is triggering a horizontal scroll bar as soon as the powder image moves off the page.

I have the powder image set to overflow:hidden and the container it’s in “hero_home” also set to overflow:hidden.

I know it’s the animation that’s triggering the horizontal scroll bar, because if it tell it to move to the inside instead of off the edge of the page, I no longer have the issue.

Any help or explanation showing me what I’m doing wrong or where else I need to turn off overflow would be greatly appreciated. Thanks!
