Different MQTT Commands from Sonor S20

Hey guys,

I just flashed my Sonoff S20 sockets with the newest Tasmota Firmware.
Now I saw a strange behaviour. When I switch the Socket from the Tasmota Web Interface it sends out the following and installed command:

19:23:38 MQT: tasmota/sonoff-******/stat/RESULT = {"POWER":"ON"}
19:23:38 MQT: tasmota/sonoff-******/stat/POWER = ON

If I send the command via the following item it sends the following command:

Switch Max_Sonoff_S20_****** "Stehlampe" 	<light> (Lights_MaxZimmer, Lights)     {mqtt=">[broker:tasmota/sonoff-******/cmnd/POWER:command:*:default], <[broker:tasmota/sonoff-******/stat/POWER:state:default]"}

Tasmota-Log:

19:24:38 MQT: stat/sonoff-******/RESULT = {"POWER":"ON"}
19:24:38 MQT: stat/sonoff-******/POWER = ON

So why are there those different commands. The problem is, that when I switch the socket via Alexa, the normal item is not updated, cause it waits for the tasmota/sonoff-******/stat command and not the stat/sonoff-****** command.

Thank you guys!!
