I have created two playgrounds to complete the challenge and I still getting errors.

One the first attempt (environment), the error is:
Challenge Not yet complete... here's what's wrong: 
Couldn't find the summation of annual revenue in the report 'High Value Residential'.
Although as the screenshot below shows, the sum is included in the report:



One the second playground the error is:
Challenge Not yet complete... here's what's wrong: 
An incorrect source report is assigned to the 'Open Support Cases' component.

And on the third one:
Challenge Not yet complete... here's what's wrong: 
There was an unexpected error while verifying this challenge. Usually this is due to some pre-existing configuration or code in the challenge Org. We recommend using a new Developer Edition (DE) to check this challenge. If you're using a new DE and seeing this error, please post to the developer forums and reference error id: HCMOJHYZ

I am having problems with this report, I get an error message:
'Challenge Not yet complete... here's what's wrong:
Couldn't find the summation of annual revenue in the report 'High Value Residential.'

The below screenshot shows the I had applied the sum. Can anyone tell me what am I missing here?
