mirror sketched entities

I am creating 3d sketch and want to mirror some sketch entities.  I was able to do it yesterday, but for some reason the mirror icon is grayed out no matter what order I try to do this. It is simple fillets and curves for know.  yesterday did it with spline.  I can draw easily enough but have several so would be nice to do at once.

I am in the sketch, selecting entities, but grayed out

Try selecting CL first then entities, same result.

thx

additional question...how to get the transition in sweep not to show line b/t fillet or spline and straight line
