How to populate ActiveAssignmentCount for Get-AzureADMSPrivilegedRoleDefinition?

when I run this command:

Get-AzureADMSPrivilegedRoleDefinition -ProviderId aadRoles -ResourceId $global:varTenant.ObjectId | Format-List

None of the results have any values for the fields I've outlined in red. For example, roles that I know have active assignments don't show any value in the ActiveAssignmentCount property. How can I get those values to populate?

I tried in my environment and got below results:

When I execute the commands and got same output like below :

Get-AzureADMSPrivilegedRoleDefinition -ProviderId aadRoles -ResourceId $global:varTenant.ObjectId | Format-List

• I have checked this MSDocs. As per my understand role definition command shows the default value for the PIM.
