Object spline has lost its motion blur area

Hi There, new Silhouette user here, working on my first Roto in Silhouette and loving it compared to other software.!

I had the motion blur set up and working yesterday, but this morning when I loaded up the project the roto shapes have lost the blue dotted outline of where the motion blur region starts and ends. The Motion blur is still active and I can see the effect of the motion blur on the clip in the Color Comp viewer. Has anyone experienced the same behaviour? I’ve attached a screenshot of my settings (the project is my own footage BTW so no issues with NDA content).

Ha Ha, just realised that I didnt have the Roto Overlay turned on in the Toolbar! all good now.
