Watcher payload entries group together in the index

[Jacky_Kwok]

I have used the transform which the output looks like this.

"payload": {
            "_doc": {
              "TransactionAmount": [
                50000,
                565
              ],
              "CompanyName": [
                "C Store",
                "A Store"
              ],
              "TransactionAmountAllowed": [
                11000,
                105
              ],
              "StoreName": [
                "C Store",
                "A Store"
              ],
              "CreatedAt": [
                "10/10/2017 16:48",
                "11/10/2017 17:05"
              ],
              "PhoneNumber": [
                33333333,
                11111111
              ],
              "TransactionID": [
                4,
                5
              ]
            }

But the data are all grouped together like this.
How can I separate the record and to create two entries?
