Explode view sketch lines not showing in drawing

I have exploded model views with sketch lines but the lines are not showing on the drawing views.

I have turned on/off the "view sketches" option (it worked in 2014) but it does not help.

Just installed 2016 SW but I don't know if that's the issue.

Any help please?  Thanks

Tim
