Challenge not yet complete in Playground 1 We can’t find a future task called ‘Call Ms. Smith'. Check to be sure you have added the task to your lead's record.

On Create and Convert Leads as Potential Customers for some reason after I click on the check challenge it comes back with "We can’t find a future task called ‘Call Ms. Smith'. Check to be sure you have added the task to your lead's record." I copied and pasted and saved it and it clearly shows correct but still comes back with the above error. Does anyone know of a solution or what I might be doing wrong?

I've tried a new "Playground", deleting cookies,...you name it and it still won't recognize the "new task" added.  It is clearly in the record and in the 'tasks' tab.  Is anyone else seeing this glitch?
