'Get Programs' API returns empty string for Status field in the response

I am pulling program details by using below API call,

/rest/asset/v1/programs.json?_method=GET&offset=0&maxReturn=200​

in the response, status field is always set to empty string

{

  "success": true,

  "warnings": [],

  "errors": [],

  "requestId": "e8f4#154cc5b6d98",

  "result": [

    {

      "id": 20369,

      "name": "Test",

      "description": "Test",

      "createdAt": "2016-03-17T04:15:17Z+0000",

      "updatedAt": "2016-04-20T15:21:28Z+0000",

      "url": "<<some url>>",

      "type": "Default",

      "channel": "Basic Email",

      "folder": {

        "type": "Folder",

        "value": 72359,

        "folderName": "Test"

      },

      "status": "",

      "workspace": "Corporate"

    }

]

}

However, I can see in the Marketo UI that 'Event Status' is set to 'Scheduled Event'. But in the response, I always receive status as blank string.

Any help would be highly appreciated.
