Post slider is not reflecting on live website.

I created a post slider for my homepage in elementor using the WPB Post Slider tool. I can see and edit the post slider in elementor but after updating, when I visit my site’s homepage to see the changes, the post slider doesn’t appear. Have a look.
Post slider created in elementor:- https://prnt.sc/udl0iu
When I visit the page, it’s not there:- https://prnt.sc/udl13o

This is the page URL where I want to have that slider(homepage):- https://smartgadgetpick.com/

Thank you!
