Display incorrectly query result from elasticsearch

I have a query for elasticsearch on redash, the result from elasticsearch is:

{
  "took": 1,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "skipped": 0,
    "failed": 0
  },
  "hits": {
    "total": 19,
    "max_score": 0,
    "hits": []
  },
  "aggregations": {
    "moduleId": {
      "doc_count_error_upper_bound": 0,
      "sum_other_doc_count": 0,
      "buckets": [
        {
          "key": "数据",
          "doc_count": 11,
          "labels": {
            "doc_count_error_upper_bound": 0,
            "sum_other_doc_count": 0,
            "buckets": [
              {
                "key": "数据自身问题",
                "doc_count": 10,
                "onesId_num": {
                  "value": 10
                }
              },
              {
                "key": "未填写原因",
                "doc_count": 1,
                "onesId_num": {
                  "value": 1
                }
              }
            ]
          }
        },
        {
          "key": "多码后端",
          "doc_count": 8,
          "labels": {
            "doc_count_error_upper_bound": 0,
            "sum_other_doc_count": 0,
            "buckets": [
              {
                "key": "未填写原因",
                "doc_count": 8,
                "onesId_num": {
                  "value": 8
                }
              }
            ]
          }
        }
      ]
    }
  }
}

As shown in the above elasticsearch query result, the “数据” key has a sub-buckets contained two keys(“数据自身问题”, “未填写原因”).
But, on redash, the result table just display “未填写原因” for the “数据” key, “数据自身问题” does not display:

Why the row which moduleId is “数据” and labels is “数据自身问题” does not display in the result table?
