@EtanaMeraki if you click on the icon it should tell you which license it is.
If it is a license for a wireless access point and you have a wireless access point without a license associated then go to the devices page and you should be able to select the AP and assign the license there.
The reason that everything is still working is that the PDL license enforcement was always flaky and sometimes doesn't disabled devices without a current license. You do still need to have purchased the licenses though.
