Need a bit of help with Sliders


I’ve recently started learning the platform and have run into a small roadblock. I’m using this cloneable theme: CREATIVE Cloneable CMS Template - Webflow

I can’t figure out how the sliders are structured in the nav bar because I can’t seem to flip through them via the style bar.

Here’s a WIP preview of the website I’m working on: Webflow - Enkayy LLC.

In addition, I noticed that my page jitters even in preview mode. I was wondering if my deletion of elements changed the spacing as well? Is there a way I can track and keep it consistent?
Would appreciate the guidance
