Hello, @Coroveisc,
I have checked your site and found that everything is set to ok, widgets and theme options all. Also, there is no such third-party plugin that conflict and causes the issue. But you are not using the latest version of the theme https://postimg.cc/LJ4hFZG7 and its core plugin so please first try to update the theme to the latest version then update the theme necessary plugins to the latest version. Then check back to your site after clearing the browser cache. I hope your issue will be resolved.
Here is an article to know how to update the theme step by step: https://xstore.helpscoutdocs.com/article/63-theme-update
