Duplicated GUIelements when print Diagram

[eadocX Support]

You have the diagram printing as ‘Diagram and all contents’, so eaDocX is doing just that: printing the diagram, then each of the elements in the diagram.
It’s then looking what to do next, and finds those same elements in the same package as the diagram, so prints them. Again.
The solution is just to make the diagram print normally: Diagram -> Diagram Options -> Normal.
