SolidWorks SplineTools greyed out for no apparent reason - Help

Hello! I'm having very annoying problem with SW 2013!!!
I have a sketch with multiple splines.

I want to add new spline points to some of my splines but I cant!!
The SplineTools are greyed out! Rightclicking does not show the Spline options to add spline Handle or to add Spline Point!!

If I create brand new sketch and make new spline, then it all works, but in my first sketch I cannot add new points to my splines!
Thanx in advance!
