If nested display item is used to show subtitle along with question text, then it also creates separate questionItemViewItem to display another question item, and its conflict.
e.g

"item": [
    {
      "linkId": "1",
      "text": "Have you taken a pregnancy test?",
      "type": "boolean",
      "item": [
        {
          "linkId": "1-select-one",
          "text": "Select one",
          "type": "display"
        }
      ]
    }
  ]

It creates 2 questionItemViewItems, where 2nd questionItemView item with linkId 1-select-one is not required in this case.

It is possible to hide/ disable nested display questionnaire item.
But then developer has to explicitly add hidden extension or make it disable.
Nested display questionnaire item is only added to provide subtitle text to parent question. Therefore, it must not create questionnaire item view item for nested display item. If nested display item not enabled then view item will not be created.

If display item is present in group item then it should not be considered nested display item for subtitle text, this special case need to be handled.

Approach 2 :
Do not include nested display item to QuestionnaireItemViewItemList at the time of questionnaire state creation.
