cambiumpmp80211GPSSyncStatusTrap only traps losing sync

cambiumpmp80211GPSSyncStatusTrap only sends trap on losing sync, not for other sync states. I observed this on a ePMP 1000 and ePMP 2000, both with version 3.4.1 firmware. Has anyone else seen this, it doesn't seem to be a known issue. If I can provide any other information let me know.
