All, I'm receiving the below error when trying this challenge.
The 'Sales Manager' dashboard does not have the correct headers and titles for the chart components.

I've tried many things including changing the base field for the Summary to the OOB fields, but it doesn't help.  My configurations are shown below and seem to match the requirements as exactly as I can find.  Does anyone else have any suggestions?  Can't find a Salesforce help for the Superbadges.
