A good test for this is to try running the SNMPwalk from the AMP CLI. This usually confirms if the controller is passing the expected information back to AirWave.
# s2w IP_address_of_controller community_string wlanAPName -Cc -On
example
# s2w 10.10.10.10 public wlanAPName -Cc -On
If you see the APs entry in the SNMP result, then there's an issue in the AirWave that would require a support case to be opened.

A workaround would be to reprovision the AP on the controller.
