"Active gateways" issue in dashboard

As you can see in the attached screenshoot I’m having an issue with the dashboard. I’ve got two gateways; both are actives as seen in the map, but the gauge says that one of them is inactive.
Moreover “Device data rate usage” doesn’t reflects some messages with DR0.

My versions are
ii chirpstack-application-server 3.14.0 armhf
ii chirpstack-gateway-bridge 3.10.0 armhf
ii chirpstack-network-server 3.12.3 armhf

Thanks in advance
