Hello, @Frankold,
I have just logged into your site and tried to edit the home page with Elementor Page Builder and it is working perfectly fine for me, here is the screenshot: https://postimg.cc/Mvt2fH37 so it must be the cache issue at your end nothing else, or might be the slow internet issue.
Please try to remove the browser cache or try to check your site on a fresh new browser, and I am sure you will not face this issue anymore.
Regards 8Themes Team.
