I'm currently trying to get my superbadge (Lightning Experience Reports & Dashboards Specialist) everything was working fine until I I was checking my answers and I got this error message:

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: BAZAAIAG

There was someone else on the forum with a similar problem, I cleared all my cache and logged into my Developer Edition. Still nothing. Any ideas? God I am so close. I just need two more to get his badge. Much help is appreciated y'all!

I'm currently working on Challenge 3 and am dealing with trying to fix this error:
Challenge Not yet complete... here's what's wrong: 
The report 'Open Support Cases' contains records of the incorrect status. Please check the filter.
 
For the Open Support Cases, I created a Custom Report Type linking Accounts and Cases and have the groupings and fields set up as specified. For the filter, I've tried "Closed equals False" and "Status not equal to Closed" for the Cases, but neither of those worked.

If anyone who has passed this challenge can provide input on what's wrong with this report. It'll be much appreciated.
