vRA 7.2 - Change "Machine Resources" on Blueprints

Hello!

I am playing around with vRA 7.2 and have created a few simple Blueprints with one "Server CloneWorkflow from Template". The Blueprint works as expected an i have created a few VMs based on the Blueprints. I like to change some "Machine Resources" (maximum CPUs, Memory or Storage) in the Blueprints and the new Settings are working for new Requests but not for the already provisioned VMs. For Example: I set the "maximum CPUs" from 2 to 4 an can request a new VM with 4 CPUs. On provisioned VMs the max. CPUs Value is not updated to 4. Can anyone confirm this behavior?
