Properly remove resources when removing the VM

Hi,

I have created a service blueprint to power off the VM and delete it from the vCenter.  The workflow works fine, but it does not seem to released the resources from vRA.

So it said, the VM has actually deleted from vSphere, but from the vRA admin portal, Managed machines, I found the VM that I have decommissioned using the mentioned service blue print now shows as "Missing"

My question is how do I decommission the VM and also removed its reserved resources properly?

Thanks,

Jimmy
