Unable to save InfluxDB 2.x source in iotaWatt

I’m trying to add a InfluxDB 2.0 uploader to my IotaWatt device, and it doesn’t seem to be giving me the green “Save” button.

Yet there doesn’t seem to be a “Save” button available yet.

Is anybody able to see if I’ve missed something, or did I misconfigure something in the InfluxDB 2.x definition?
