Guided Tour for Employee Center

[samadam]

I am trying to create guided tour on Employee Center. I want to include Header (My Tasks, My Requests) and My Active items(Requsts, Survey) . My active items works but when the step comes to Header tasks I get an error : This is happening for My Tasks, My Requests.

"Tour ended because step was not found". 

What am I missing? Also how can I set the tour to give an option for the user to take the tour or opt out of it?

Once I am Guided Tour Designer in Employee center. I click on the menu on the right to select the tasks and requests.
