Circles shown on rebar ends in 2D

Hello, 

After cutting sections in my 3D model I noticed that once the 2D model is created I am getting circles on all my bent bars. 

Please see the attached photo of my 2D rebar model.

Is there a way to turn these circles off in the drawing file or .sys file so that we do not have to show them? If we can't turn them off is it possible to minimize the size of them?

 

Thanks
