PageBuilder Issues – loads but does not edit

I am currently trying to create a new website using the Create Theme from ThemeTrust (http://themetrust.com/themes/create/). I have been having problems with pagebuilder not working correctly. I can’t add new rows, widgets or even prebuilt layouts when using pagebuilder. I can add content using the visual or text editor.

I have tried deactivating all plugins besides pagebuilder and it still does not work. I am not sure if this is more of a problem with pagebuilder or with the theme. ThemeTrust suggested it may have been a Wordfence issue but I have deactivated Wordfence with no solution.

Any help would be appreciated! Thanks!
