I've competed all steps in challenge 2 on the Process Automation Specialist Superbadge, but when I check it, an error comes back saying

"Challenge Not yet complete... here's what's wrong:
There was an unexpected error in your org which is preventing this assessment check from completing: System.DmlException: Insert failed. First exception on row 0; first error: FIELD_CUSTOM_VALIDATION_EXCEPTION, Both Billing Country and Shipping Country must be populated. Can be US, USA, or United States: []"

Here is the rule I set up. I tested it and it works. Any idea what is going wrong?

 

I'm completing the Lightning Experience Reports & Dashboards Specialist Superbadge, and when I check Stage 7, it comes back with an error and tells me to post on here.
Error - 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: DCXTLCTI

Can someone please help me out with this??
