Strange Hue command

I would like to change hue bulb to (“11,100,100”), then start the alert with “LSELECT” and finally change the bulb to (“50,50,0”). It works with this exception: after changing the bulb to (“50,50,0”) a command is executed which changes the bulb to (“11,100,0”). I don`t know from where this command was launched. Any ideas ?

Color Color_EG_Wohnzimmer_WoZ1 "Lampe1 Color Wohnzimmer" <colorlight> (EG_Wohnzimmer,Lampen) {channel="hue:0210:00178876c049:1:color"}
Dimmer CoTemperatur_EG_Wohnzimmer_WoZ1 "Lampe1 Farbtemperatur Wohnzimmer" <qualityofservice> (EG_Wohnzimmer, Lampen) {channel="hue:0210:00178876c049:1:color_temperature"}

rule "Alert Test"
when
   Time cron "0 7 20 * * ?"
then {
 	 	Color_EG_Wohnzimmer_WoZ1.sendCommand("11,100,100")  
        Alert_EG_Wohnzimmer_WoZ1.sendCommand("LSELECT")    
        Thread::sleep(30000)
        Color_EG_Wohnzimmer_WoZ1.sendCommand("50,50,0")
     }
end

Any solutions here?
I have got a similar behaviour: The following rule works fine, but 15 seconds after the “LSELECT”-Command there appears a “[…] changed from LSELECT to NONE” in the log. I cannot find where it comes from:

val Number FeuchteGrenze = 65
rule "Alarm bei Feuchte im grossen Bad"
when
    Item BadGrossFeuchte changed
then
    if(BadGrossFeuchte.state as Number >= FeuchteGrenze) {
        var HSBType blinkLichtFarbe = HSBType::BLUE
        lEssbereich_Color.sendCommand(blinkLichtFarbe.toString)
        lEssbereich_Alert.sendCommand("LSELECT")
    }
end
