Customize an org to support a new business unit - trailhead error message

I am struggling on the first unit. When I enter the details for Fumiko Suzuki and then hit Save and New, I get an error message saying it is a duplicate username. I have changed the username several times to account for this, but each time it comes up with the same message. I’ve set up a new trailhead playground and the same thing is happening. Any ideas will be appreciated!
