I'm on the "Visualizing Your Data" unit and I got down to the challenge which I believe I completed correctly but I get this error:

Challenge not yet complete... here's what's wrong: 
One or more of the following is incomplete in the Dashboard: no component uses the 'Cases by Status' report as a source report, your component does not have a 'Cases by Status' header, and/or your component does not have a 'New vs Closed' title.

I've checked this five or six times and have created the dashboard twice.  Not sure how to progress from here.  Any help will be greatly appreciated.

I am doing Trailhead "Reports & Dashboards - Visualizing your data" Challenger and keep getting above mssage

"Challenge not yet complete... here's what's wrong: 
The 'Cases by Status' report does not include the Owner and Account Name columns"

Here is the reprt few lines with header"

Case Owner Subject Date/Time Opened Age (Hours) Open Closed Account/Full Name Account Owner Alias Account Owner Account ID
Status: New (9 records)
