I was finishing up the Create a Lemonade Stand project in Trailhead. Even after completing it with no skipped steps on two different occasions, I receive this error:

Challenge Not yet complete... here's what's wrong: 
The 'Pending Orders by Queue' report does not appear to be grouped by Fulfillment Queue Name and Flavor Name. 
Note: you may run into errors if you've skipped previous steps.

Except that my 'Pending Orders by Queue' report is grouped by Fulfillment Queue Name and Flavor Name.

Is this an error with the Trailhead?
