contact form7 not displayed on pages designed with page builder

I have just discovered, that all new pages which are designed using the page builder dont show the contact form7 field. All other pages, which were created with the standard template (WP Hoot Chromatic Premium Child Version) are fine. Can you please let me know how to activate contact form7 for the pages using SiteOrigin Page builder?

A page using the standard template: http://www.allesmitschaf.com/unternehmen/allesmitschaf/
A page using page builder: http://www.allesmitschaf.com/kategorie_test/ (Testpage)
