Having trouble with some tool pasts

Open contour/ closed contour

Hi everyone , I have a quick question. When im in the cutting tab in manufacture, and I go to highlight the lines I want cut it always highlights the actual line as well as the dotted line beside it, if that makes any sense. if I click on the line again, I can choose between open and closed contour. is there a way to set this so that I don’t have to double click every line?
