linetypes of referenced drawings in the sheet dont work

Hello, DS seems to have problems with the proper display of linescales/linetypes of referenced drawings on the sheets.

I reference the drawings in the layout sheet file. In the model the lines are ok. In the sheet they are shown as continues lines. I also inserted the referenced drawing as block and in the sheet the lines work fine. In Autocad the file works fine. Any Idea?
