Line styles in callout don't apply when exported to DWG

Hi

I have some problems with my DWG-exports from Openbuildings. The elements I've drawn in my designfile and are hidden are in my drawing file shown with a dashed line. Like this:

The problem now is that when I export this to DWG all those lines from my callout are continues in autocad. 

Lines I've drawn in my drawingfile using line style 1-7 are all shown as expected. What is the reason for this? What setting do I have to change? 

Regards,
