Why is this code making the menu come up twice?
menulist = Split("Answer;Ignore", ";")
ShowMenu ("Therapist : Why do you blame yourself for your friends death", menulist, false) {
if (result = "Answer") {
msg ("You: Do You believe that if you die in your dream you die in real life? See I killed my friend in my dream and he died in real life.. plain and simple.")
msg ("The therapist takes notes")
SetTimeout (3) {
play sound ("Door Kick sound effect.mp3", true, false)
OutputTextNoBr ("Someone in kevlar armor kicks down the door, knocks the therapist out and then you get knocked out.")
play sound ("skypesmsto_35vqfqpz 2016-11-27 09.05.02.wav", true, false)
MoveObject (player, Cell)
}
}
else {
OutputTextNoBr ("Therapist: Ignoring me wont help you, I know you think that you killed your friend but that's impossible, He died of a heartattack.")
play sound ("Door Kick sound effect.mp3", true, false)
OutputTextNoBr ("Someone in kevlar armor kicks down the door, knocks the therapist out and then you get knocked out.")
play sound ("skypesmsto_35vqfqpz 2016-11-27 09.05.02.wav", true, false)
MoveObject (player, Cell)
}
}

I just tried it in test game with the play sound lines removed (as I do not have the files), and it works fine. Either it is the sounds or something else in your game.

I have no experience of using sounds, but you could comment out those four lines by putting // at the front and see if it still happens. If it does, it is not the sounds, and you need to look elsewhere.

inexperienced user here, but could it possible be because you put the Split before the ShowMenu?

unfortunately that's not it, but good guess at it.

the 'split' is a Function that creates a list and then returns that list, which is then being stored/saved/set into the 'menulist' Variable. That 'menulist' Variable is then used by the 'ShowMenu' Function, providing the 'ShowMenu' Function the needed list (as a Parameter/input, being that list, to be used within the 'ShowMenu' Function) as the Value of the 'menulist' Variable.

it's working almost exactly like this in math algebra:

menulist : x
the created list : 4
ShowMenu : y
ShowMenu's other Parameters/Inputs (question message, and whether to be able to cancel out of ShowMenu during game play or not): + 5

x = 4
y = x + 5
// y = 9

// the '4' is being used only once (aside from it being set/stored/saved into the 'x' Variable) to produce the 'y = 9'

// and like-wise, the 'created list' (created via the 'split' Function) is being used only once (aside from it being set/stored/saved into the 'menulist' Variable) to produce the in-line menu during game play via the 'ShowMenu' Function and its use of the inputted 'created list' (via the 'menulist' Variable as a Parameter) for its usage
