Wrong topic with sonoff 4 channel switch

Hi, i’m starting with HA and sonoff devices and have an issue with the MQTT auto-discovery of the sonoff 4 channel device with the tasmota firmware.
When i set the %topic% in the sonoff device at ‘4channel’ and start the auto-discovery in the console (setoption 19 on)
The console output gives me this.

That looks OK for me. But within HA the newly discovered device looks like the attached image.

I don’t understand why the switch are named with ‘switch.sonoff’ instead of ‘switch.4channel’ as i expected. What am i doing wrong ?
