MQTT Hub device is not logging to Influxdb

I am using the latest version of the InfluxDB app and the MQTT Hub app. I have added several devices through the MQTT Hub. The devices are working correctly and are displaying the meter readings as expected.



However, these devices are the only ones that are not being logged to InfluxDB. I cannot find a single entry for them in the database.

Any idea what could be wrong here?
