Rhino 6 Introduction Step by Step - question

Following Rhino 6 Introduction Step by Step; I get stuck after 2.2 Curves. The system does not allow me to proceed although I have finished this block (not a “Continue” button like before). Is it a bug here? I realize this is not the same course as the one above but perhaps you can clarify?

Hi Ingemar -
Since this didn’t have anything to do with that other thread, I moved your post to a new thread.
Could you please describe which guide you are looking at and clarify which system doesn’t allow you to proceed?
