Interview successful, device working - but nothing in config

Hi there,

I am using Zigbee2MQTT for a while now and have paired over 20 (23) devices with my dongle/coordinator. This works really well, but yesterday when pairing a new bulb (IKEA LED1842G3, something funny happened, which was new:

The interview was finished successfully and the device is “commandable”, but it’s not showing up in the configuration.yaml - neither in the database. I wanted to setup an additional “device specific” parameter, but it’s just not there.

Adding it by hand (to the config) and restarting zigbee2mqtt did nothing.

Thank you!
