Home page doesn't look like demo

I have a theme.Demo:
https://themes.wpbusinessbundle.com/hyperion/

Here is 3 featured info box & the blog-post & latest news. I can’t make them work on my site. the URL – https://seo-specialist.net/

How can I work on?

I have configured the option in theme control panel. Buy no result. I used latest post as default. If i use static font page, the slideshow doesn’t work.
