I am trying to do the Lightning Experience Chatter Basics for Admins trail. I am on the Approve Records from a Chatter Feed and when I try the challenge with creating the Approval Process, I am instructed to create the process and set the typing in Allison Wheeler does not work as the User does not exist. Should a new trailhead playground be created?

Has anyone experienced the Trails Completed count on their profile not increasing? I completed the Admin Beginner Trail last week and haven't seen my number of Trails Completed go from 0 to 1 - https://trailhead.salesforce.com/en/me/danny
