Trouble correcting number of cores in CF2021 Activations

We recently purchased 6 licenses for CF2021 Standard with the understanding that 1 license covers 2 cores, and we're intending to install this on 6 virtual machines configured with 1 socket/2 virtual processors (2 cores).  Unfortunately, I didn't realize that two of my servers were configured with 4 cores (2 sockets/4 virtual processors) when I did my first installations.  The License Usage tracking showed them as activated with 4 cores.  I had my sys admin restart the servers with 2 cores each (verified in Windows) and then deactivated and uninstalled CF2021 from each one.  I thought that by reinstalling, they would "reset", get a new device ID and activate with the correct number of cores.  However, after reinstalling, they still show up with the same device ID and are now "re"-activated, still with 4 cores.  My worry is that by each using up twice as many cores as they actually have, I'm going to run out of licenses before I can get all my servers installed.  Does anybody know how to truly reset this?  Is that something I have to go to Adobe to do?
