Tasmota device partly functioning

I have a Calex lamp that I flashed with Tasmota 10.0.0. It is detected by the MQTT discovery plugin, but

it is identified as a Color Switch, WW, Dimmer instead of Color Switch, RGBWW, Dimmer
it can be controlled from the Domiticz dashboard, but the dashboard widget is not updated to reflect the actual state.

When using the MQTT Client Gateway with LAN interface I can set it to Color Switch, RGBWW, Dimmer and the widget is fully functional.

Did I overlook a critical setting?
