Azure Policy Assignment name discrepancy in powershell output and azure portal

Question

Hello ,

I am working on a pester test with a policy with some powershell scripts , i have deployed 2 storage accounts in azure and both are compliant with the policy which i have assigned.

The powershell output different AssignmentName for one of the storage account. one appears to be correct and another one has a diffrent name in powershell view , but whereas the azure portal has a single assignment name for both of the storage accounts deployed.

Could you please share your views on this ..

Thanks in advance your help
