Activated Pagebuilder breaks homepage layout

I’ve installed the wordpress theme sweethome that comes with the wordpress plugin siteorigin but it breaks the layout/css of the home page. the website is https://www.belizepropertyportal.com

Note that prior to this about a month ago or I must say when I initially installed it back in May it worked fine with the theme but the last update is when I noticed the problem. It’s new website.
