Thanks for getting back to us, @MikeFord.
Allow me to chime in and share additional details about the difference between the users that were added to the license and users that were not.
If you click the box beside to Add this user to my QuickBooks license this will allow users to work with your company file at the same time. Then, your purchased license will be deducted once you click the button and they have a license seat in your company file.
While for the other user, they're the ones who will access the company file without a license. You can control what type of access you'll be adding to this user like full access, view only, etc.
