I have just activated a private pro subscription and attached one machine. But my 'Pro Dashboard' lists two attached machines. How can I get a list of the attached machines from the dashboard?

You can obtain an active machine count through the Ubuntu Pro Dashboard for each subscription to Ubuntu Pro. This gives the number of online machines attached to your Pro token that have pinged Canonical Servers within the last 24 hours. If a machine is detached from your token the reduction in active machine count will not be seen for 24 hours until 24 hours later.
See https://documentation.ubuntu.com/pro/active-machines/
The man page which explains further how to manage the Ubuntu Pro services from Canonical can be viewed here and is your official reference.
For example, it provides a list of commands which can be used in relation to the management of your subscription including status which indicates whether the service is enabled on the machine where the command is performed, as well as status --simulate-with-token which will shows whether the service is set to be enabled when that token is attached.
As you attach machines, you will see your active machine count go above your license count. This is expected behavior and will not impact your access to the Pro services.
There will always be a discrepancy between active machine count and license count. I got this off of UBUNTU site
