Azure Tenant Billing Scope Troubleshooting

I'm having issues with my Azure tenant set up, specifically with the Azure subscription billing scope. The billing data seems to be appearing incorrectly. I haven't made any recent changes to my Azure subscription that might have affected the billing data, but I'm not entirely sure.

- Troubleshoot the Azure subscription billing scope
- Correct any issues with the billing data

Ideal skills for the job include:
- In-depth knowledge of Azure and its billing system
- Experience in troubleshooting Azure issues
- Ability to explain technical issues in simple terms
