Hello, @Diana Nikolova,
Your issue has been solved please check back to your site now after removing the browser cache.
I have turned OFF the XStore Ajaxify from the banner element settings which was creating this issue on your site: https://postimg.cc/gr8ytMxS
And now it is working fine please watch this video I have created for you as a result: https://www.veed.io/view/988920ec-8158-4cc2-945f-f5bd43b1397c?sharingWidget=true
I have done it for you for the first banner only, for 2nd and 3rd banners, you can do it by yourself.
Regards 8Themes Team.
