SQL servers on machines AMA Not Reflected In Resource Count

I have enabled SQL servers on machines at a subscription level:

I can see that the protection has been enabled on the SQL virtual machine resources within the subscription:

I can also see the ATP and Scan status data being ingested into the configured Log Analytics workspace as well as vulnerability assessment results on the SQL virtual machine under Microsoft Defender for Cloud so all seems to be working.

The issue is that Defender is not reflecting Resource quantity:

Is anyone able to advise why this would be the case and how I can go about getting this to update?

I am using the custom Log Analytics workspace option which is situated in a different subscription.

I have also noted that a subscription with the legacy Log Analytics agent solution for the SQL servers on machines seems to reflect the Resource quantity correctly, could this be the difference?
