Page Builder by SiteOrigin – can't insert a image per widget ('add Image'-Btn)

If i will use a Widget with standard ‘select image from media’-dialog per ‘add image’ button i have no effect alfter click. I think its a problem with fireing the event.

When i use the widget in theme directly all is good, all works. Only in Page Builder the widgets (to insert a image with described functionality) not work.

Has anyone an idea to solve the problem?
