Verifying Acrobat Pro 2015/2017 License Use Reported vs Actual?

We have installed, uninstalled, reinstalled Acrobat Pro many times on different PCs.  Sometimes we take a workstation that has Acrobat Pro installed, format the hard drive, reinstall Windows without reinstalling Acrobat since the new user doesn't need Acrobat and then reassign the computer to another user.  So, it may look to Adobe as if we are still using this license since Acrobat was never uninstalled and deactivated.

How can we see how many licences Adobe thinks we are using and compare it to how many are really still installed on active computers and remove any extras to make the licenses available again?

I signed into the Adobe License portal and see serial numbers and download links, but I don't see where it says how many licenses Adobe says are used out of available licences.
