Start Button Missing? Tried other solutions

Options

I am in the unique position of content creator/instructor/admin and am switching to 'view as learner' to ensure quiz is working. The start button is missing completely and is not visible to my colleagues. I have already checked other problems in forums and have the following:

 

-Start and End dates complete

-Users are enrolled

-Published and course is active

 

I am really stumped on this one! I would appreciate your help.
