Unexpected behavior of Json

I am trying to create a Json, in which a question have value, option and also it contain multiple questions. and these sub questions can also contain multiple sub questions.

here is my Json string

   {
  "Questions": {
    "question": {
      "Value": " Quest 1",
      "Option": " Quest 1 Option",
      "question": {
        "Value": " Quest 2",
        "Option": " Quest 2 Option"
      },
      "question": {
        "Value": " Quest 3",
        "Option": " Quest 3 Option",
        "question": {
          "Value": " Quest 4",
          "Option": " Quest 4 Option",
          "question": {
            "Value": " Quest 5",
            "Option": " Quest 5 Option"
          },
          "question": {
            "Value": " Quest 6",
            "Option": " Quest 6 Option"
          }
        }
      }
    }
  }
}

But when I'm trying to see it in Json Viewer,ques 2 and ques 5 is missing. what I'm doing wrong here ?
