Cannot select point of a 2d sketch in 3d sketch mode

I keep having this issue where I create a 2d sketch and link up points in a 3d sketch. I go back later and I can no longer select any of the points from the same 2d sketch  I linked up previously. Screen shot below, sketches show no errors but yet I can only select the points on the 2D sketch that were linked initially I cannot select any new points. Any idea guys? This is driving me bonkers !
