I am stuck on the R&D superbadge.  I have tried several different things on my contacts without hobbies report and keep getting a report configured incorrectly message.  Here are some screen shots of my report, formula and bucket field.  Please let me know what I am missing.

I have tried this process builder challenge several times and different ways and still get an error message.  Here are the screenshots of what I am trying:



When I test the process it works, however, I get the following error message from the trailhead:
Challenge not yet complete... here's what's wrong: 
An update to an account record failed to update the mailing address fields of all child contact records. Make sure that the process is correct and that it is activated.

Can you please tell me where I have gone wrong?
