Image Not Showing Up

I work as descriptive in the instruction.
“If am working in Page Builder the easiest way to insert media is via the Visual Editor widget.
To get access to this widget first install: http://wordpress.org/plugins/black-studio-tinymce-widget/.
Once installed you’ll be able to add it via the + button in Page Builder, just search for Visual Editor.
There is an Add Media button in the widget.”

But the image i added to a site is not shown.

If i disable the plugin page builder i see the pictures.

Thanx Martin
