Troubleshooting Sticky Components in Webflow Projects with Relume

Hi there, I'm working on a Webflow project that did not initially include the Relume style guide. I manually created a style guide page and imported the necessary Relume components. However, components like layout415 are not functioning as expected — it is supposed to stick to the top of the viewport, but it's scrolling past instead. To troubleshoot, I created a separate Webflow project by cloning the official Relume style guide and copied the same components from the first project. In this new environment, everything works perfectly, including the sticky behavior. Here are the read-only links for reference:

I’d really appreciate any guidance on what might be missing or misconfigured in the first project that’s preventing the sticky behavior from working correctly. Thank you!
