Live lorawan frames are visible but last seen at never

On chirpstack app , have configured gateway and chirpstack network server for EU868 frequency. Few things are working and few are not:
Gateway->Live Lorawan Frames
Gateway–OTAA end device activation
Application–>Enddevice–>Lorawan Frames
i do also get the device address after OTAA join process.
Not working:
Gateway–Last seen at never
End device-- Last seen at never
End device does not show any device data but data appears in lorawan frames with device address.
Any idea what i am missing or suggest what more information needed to find the issue.
Logs/status here for your reference:

sudo journalctl -u chirpstack-network-server -f -n 50

sudo journalctl -u chirpstack-application-server -f -n 50
