Your video link doesn't work, you need to upload the video to some file sharing service or youtube.
But more importantly, you need to share your project file, or additional screenshots of your code. From what I can see, the problem may be with the "State machine3" group. Or possibly you have other "Demon MoveTo arrived" events somewhere else, which may trigger simultaneously and mess with the logic.
Also, remove "Wait for previous action to complete" action, this is the wrong way to use it.
