Google Form AppScript - Item choices disappear when viewing, however it's showing in editing view?

问题

I created an add-on to import questions & choices as multiple choice items in Forms.

The questions, answers & correct answer were imported perfectly and shows as expected in editing view, however when previewing the form/quiz, some questions have choices missing.

Any ideas?

function createMCQ(k) {
  var form = FormApp.getActiveForm();
  form.setIsQuiz(true)
  .setShuffleQuestions(true)
  .setAllowResponseEdits(false)
  .setLimitOneResponsePerUser(false)
  .setCollectEmail(true)
  .setShowLinkToRespondAgain(false);
  
  
  for (var i = 0, len = k.length; i < len; i++) {
    var item = form.addMultipleChoiceItem();
    item.setTitle(k[i].question)
    .setPoints('1')
    .setRequired(true)
    .setChoices([
    item.createChoice(String(k[i].a), Boolean(k[i].answer =='A')),
    item.createChoice(String(k[i].b), Boolean(k[i].answer =='B')),
    item.createChoice(String(k[i].c), Boolean(k[i].answer =='C')),
    item.createChoice(String(k[i].d), Boolean(k[i].answer =='D')),
    ]);
  }
}

Where it's imported from object like so;

"questions": [
    {
      "course": "GCSE AQA Biology",
      "question": "State the equation that links magnification, image size and actual size.",
      "a": "Actual Size = Image Size / Magnification",
      "b": "Actual Size = Magnification / Image Size",
      "c": "Actual Size = Resolution / Magnification",
      "d": "Resolution = Image Size / Magnification",
      "topic": "Cells",
      "answer": "A",
      "id": 2
    },
    {
      "course": "GCSE AQA Biology",
      "question": "Which type of microscope has higher magnification and resolving power?",
      "a": "Light Microscopes",
      "b": "Magnifying Glass",
      "c": "Super Microscope",
      "d": "Electron microscopes",
      "topic": "Cells",
      "answer": "D",
      "id": 3
    }
]

Items imported perfectly as shown when editing:

However, when previewing form, the choices for some of them missing:

This is very random i.e. not isolated to certain questions.

Any suggestion would be appreciated!

I think I managed to fix (?) this;

When adding the multiple choice item, I added the choices first before any other properties:

k.map(e => {
    var item = form.addMultipleChoiceItem();
    item.setTitle(e.question)
    .setChoices([
    item.createChoice(String(e.a), Boolean(e.answer =='A')),
    item.createChoice(String(e.b), Boolean(e.answer =='B')),
    item.createChoice(String(e.c), Boolean(e.answer =='C')),
    item.createChoice(String(e.d), Boolean(e.answer =='D')),
    ])
    .setPoints('1')
    .setRequired(true);
})

Using map instead of for doesn't have to do with anything tho.

I did a few tests, and it looks like the answer choices no longer disappear. Fingers crossed! Might be a Google's bug?
