I'm having trouble verifying a step in the Customize an Org to Support a New Business Unit. (https://trailhead.salesforce.com/projects/customize-an-org-to-support-a-new-business-unit/steps/manage-user-access) I've reviewed the setup a handful of times and even created a new playground and still receiving same error message:
Challenge Not yet complete... here's what's wrong: 
Could not find a user name 'Fumiko Suzuki' with the configuration specified in the project. Please check the step again.
