Background-Image in PageBuilder doesn’t work

Hi,

in an actual test-environment i’ve built this page:
http://stefan-bee.de/customer/hipp-drehteile/wordpress/I want to see a fixed background-image on every page – but it doesn’t work.
For test purposes i’ve set the image colour of a certain row to yellow – that works.
But it seems as would the Pagebuilder-Plugin override the background-image.

When i’m creating a “normal” page without Pagebuilder the background-image will be shown (see: http://stefan-bee.de/customer/hipp-drehteile/wordpress/zertifizierung/ )

How can i solve this?

Thank you,

Stefan
