After importing your AV key you see the following in deployement information:
The UNKNOWN state will be populated once you have deployed one or more clients but they have not yet reported back with an inventory scan.
The license expiration starts once a client is deployed and the license is used. Before the license is actually used, the expiration date and node counts are not known.
We can only get the license information from an existing client install, which is reported back to the core by an inventory scan.
