Enigma2 answers automatically without pressing any key on the remote

Good evening,
I have a problem with the enigma2 binding.

When I send a question to the Dreambox the answer is sent automatically without me pressing the button.

here is my configuration:
mything:

Thing enigma2:device:1921681786 "DB8000" @ "Wohnzimmer" [host="192.168.178.6", refreshInterval="5",timeout="10"]

myitem:

String  DB_Answer  "Answer: [%s]"   <text>   { channel="enigma2:device:1921681786:answer" }

myrule

rule "DreamBox"
when
    Item OH_test changed or
    Item DB_Power changed to ON
then
    val actions = getActions("enigma2","enigma2:device:1921681786")
   if(null === actions) {
      logInfo("actions", "Actions not found, check thing ID")
      return
   }
    //Abfragen ob die TV Sene aktiviert werden soll
    actions.sendQuestion("Soll das Licht für's Fernsehengucken aktivert werden?", 10)

end

rule "Enigma2_Answer"
when 
    Item DB_Answer received update
then
   val actions = getActions("enigma2","enigma2:device:1921681786")
   if(null === actions) {
      logInfo("actions", "Actions not found, check thing ID")
      return
   }
   logInfo("actions", "Answer is " + DB_Answer.state)
end

myFrontail

What can it be? Why does the binding do this?

No one can help me?

Well… my workaround is:

    actions.sendQuestion("Soll das Licht für's Fernsehengucken aktivert werden?", 10)
    actions.sendRcCommand("RIGHT")

After sending the question, I send an RC command after it so that NO is selected first. And the confirm is only done on the remote control.
It works for me. But maybe someone has a better idea. Or knows that it is because of the binding.
