Sending a transaction group does not work when merging transaction.Transaction with raw transaction

[pipaman]

If I create 2 txs one using an transaction.Transaction and the other a raw transaction in this way:

	let params = await algodClient.getTransactionParams();

	let suggestedParams = {
		"genesisHash": params.genesishashb64,
		"genesisID": params.genesisID,
		"firstRound": params.lastRound,
		"lastRound": params.lastRound + 1000,
		"fee": params.minFee,
		"flatFee": true
	};

	let oracleFeeTx = algosdk.makePaymentTxnWithSuggestedParams(consumerAccount.addr,
		oracleOwner, oracleFee, undefined,
		new Uint8Array(0), suggestedParams);

	let oracleTx = {
		"from": oracleTealAddr,
		"to": oracleTealAddr,
		"fee": params.minFee,
		"flatFee": true,
		"amount": 0,
		"firstRound": params.lastRound,
		"lastRound": params.lastRound + 1000,
		"genesisID": params.genesisID,
		"genesisHash": params.genesishashb64,
		"type": "pay"
	};

	// Store both transactions
	let txns = [oracleFeeTx, oracleTx];

	// Group both transactions
	let txgroup = algosdk.assignGroupID(txns);

	// Sign each transaction in the group with
	// correct key
	let signed = []
	oracleFeeTxSigned = oracleFeeTx.signTxn(consumerAccount.sk);
	signed.push(oracleFeeTxSigned);
	let oracleTxSigned = algosdk.signLogicSigTransaction(oracleTx, lsig);
	signed.push(oracleTxSigned.blob)

	let tx = (await algodClient.sendRawTransactions(signed));

I throws and error when sending the transactions:
text:"TransactionPool.Remember: transactionGroup: inconsistent group values: AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA != AB7RGLOYELISNZCFA5XJOI2IXZV2TG4LXAH5ZXD2X6B3JLB52GBQ"

If I change the code to use transaction.Transaction objects for all the txs in the group it works:

	let params = await algodClient.getTransactionParams();

	let suggestedParams = {
		"genesisHash": params.genesishashb64,
		"genesisID": params.genesisID,
		"firstRound": params.lastRound,
		"lastRound": params.lastRound + 1000,
		"fee": params.minFee,
		"flatFee": true
	};

	let oracleFeeTx = algosdk.makePaymentTxnWithSuggestedParams(consumerAccount.addr,
		oracleOwner, oracleFee, undefined,
		new Uint8Array(0), suggestedParams);

	let oracleTx = algosdk.makePaymentTxnWithSuggestedParams(oracleTealAddr, 
	    oracleTealAddr, 0, undefined, 
	    new Uint8Array(0), suggestedParams);

	// Store both transactions
	let txns = [oracleFeeTx, oracleTx];

	// Group both transactions
	let txgroup = algosdk.assignGroupID(txns);

	// Sign each transaction in the group with
	// correct key
	let signed = []
	oracleFeeTxSigned = oracleFeeTx.signTxn(consumerAccount.sk);
	signed.push(oracleFeeTxSigned);
	let oracleTxSigned = algosdk.signLogicSigTransactionObject(oracleTx, lsig);
	signed.push(oracleTxSigned.blob)

	let tx = (await algodClient.sendRawTransactions(signed));
