Missing buttons for new Rhino 6 commands

I can not find the buttons for some new commands in their respective toolbars. For example, I do not see the Catenary Curve in the Curves toolbar, Add Guide Lines in Curve Tools, Move Iso (this one could be assigned as RMB to Extract Isocurve), and so on. In fact most of the buttons shown in the New in V6 toolbar do not show in the toolbars identified in the Help file as their locations. Am I missing something?

Hi John - run ToolbarReset and restart Rhino - any better?

Yes, this worked. Thanks Pascal.
