For the same txid, why is the "status" returned from getTransactionReceipt different between versions 5.5.2 and 6.0.6?

I am trying to upgrade a node from version 5.5.2 to 6.0.6. But I am confused. For a successful transaction, getTransactionReceipt will return "status" to 1 on version 5.5.2. However, in version 6.0.6, "status" is 0 for the same txid.
Example:
txid: "0x57c6759aa9cd4ab72f60dc0f50f2bd122b00750425f0d7130bd83624424f0837"
on 5.5.2

{
  "blockHash": "0x5f42e57715275fcf44285e94cd187364f3060110e8b77fca0402b2420336b1ce",
  "blockNumber": 8544487,
  "contractAddress": null,
  "cumulativeGasUsed": 21000,
  "from": "0xdf7d7e053933b5cc24372f878c90e62dadad5d42",
  "gasUsed": 21000,
  "logs": [],
  "root": "6e1a89091922a0194173be1ac6159f2425cfda45c0e5d2898e586f4934d13f2f",
  "status": 1,
  "to": "0xb978fba16b86b4406bbed13f7d8719ed85a32cf4",
  "transactionHash": "0x57c6759aa9cd4ab72f60dc0f50f2bd122b00750425f0d7130bd83624424f0837",
  "transactionIndex": 0
}

but on 6.0.6

{
  "blockHash": "0x5f42e57715275fcf44285e94cd187364f3060110e8b77fca0402b2420336b1ce",

  "transactionIndex": 0
}

Also: ethereumproject/go-ethereum#722

in 6.0.7 beta, getTransactionReceipt's "status" value is always 0.
but, 0 is 'failed'.
