Missing event properties in extracted data

[michalpierog]

Some properties are not visible in results table when running extraction query.
Part of response from extraction request:

...
    {
      "name_2": "new_some_name_sourceCollection10001___0",
      "source_collection": "sourceCollection10001",
      "myInt_2": 537252724,
      "value_2": 0.874219398759734,
      "keen": {
        ...
        "id": "5d7f34fe60b2693fb2f2c44a"
      },
      "nested_2": {
        "finishTime": "2019-09-16T07:04:03.899Z",
        "timeStart": "2019-09-16T07:04:03.898Z",
        "nestedName": "name_sourceCollection100010"
      }
    },
    {
      "source_collection": "sourceCollection108",
      "name": "new_some_name_sourceCollection108___9988",
      "value": 0.16490727163355812,
      "nested": {
        "finishTime": "2878-03-27T11:34:41.175Z",
        "timeStart": "2018-07-31T10:02:41.175Z",
        "nestedName": "name_sourceCollection10828"
      },
      "keen": {
        ...
        "id": "5d7f350160b2693fb2f2e2ed"
      },
      "myInt": -1609691526
    },
...

Columns visible in table:
name_2, source_collection, myInt_2, value_2, keen.timestamp, keen.created_at, keen.copy.source_id, keen.copy.run_id, keen.id, nested_2.finishTime, nested_2.timeStart, nested_2.nestedName
So myInt, value, name, nested etc. are missing. The same for downloaded data. Bulk CSV extraction to e-mail works fine and contains all properties. Missing properties are also available as target property in drop-down for other analysis types.
