I see you've marked your Studio Pro version as 9.6.0. The workflow learning path uses version 9.10.1.
Workflow was not officially released untill version 9.10 if I remember correctly. In any version before that workflow still was in the beta test phase, which means a lot has changed from earlier versions to 9.10. One of the largest differences being that earlier versions also required an instance object.
Upgrade to 9.10.1 or higher so the instructions in the learning path will match up to what you're seeing in the Studio Pro.
