Quorum transaction not mined and no address

Question

I am running a private Quorum chain consisting of 3 nodes with raft consensus. When I deploy a contract to the chain via web3 I get returned a hash and can then look up the transaction with the local geth console (geth attach qdata/geth.ipc) and check its status with eth.getTransaction(hash), so I get this:

{
  blockHash: "0x0000000000000000000000000000000000000000000000000000000000000000",
  blockNumber: null,
  from: "0xc58a28d310c76e8298fa086381e6f2da9f046c07",
  gas: 4700000,
  gasPrice: 0,
  hash: "0x75bf6fc10400fa493851b8105973e9b5aab2955dc5d87d217f13ed9562ccafbd",
  input: "0xc2f448268ee5019782beeaee884bc92112187a16af7b23df948fd0f867ecb2f41f34f34e477e2ddd53c74ef20fc48b0ebcda0a003f991f9c6e1a4bedfc65288d",
  nonce: 0,
  r: "0x3cd6c0a90a9b2367d6d47f081ad8509ea374f4db54bbf51eb9ace8360e50bc7a",
  s: "0x6d6cabc76a0d7774ada6ba753d06be0400353a5d3d42d85c92c4db7b8ad2f7bd",
  to: null,
  transactionIndex: 0,
  v: "0x26",
  value: 0
}

But there is no address! So why is the transaction still not mined?

EDIT: Here is the code I used to deploy the contract:

const Web3 = require('web3-quorum');
const web3 = new Web3(new Web3.providers.HttpProvider('http://..SERVER_ADDRESS..:22000'));

var abiArray = [{...ABI...}];
var simpleContract = web3.eth.contract(abiArray);
var bytecode = "0x6080604052348...";
const account = '0xc58a28d310c76...';

var nonce = web3.eth.getTransactionCount(account);
const contractData = {
    from: account,
    data: bytecode,
    gas: 0x47b760,
    privateFor: ["oUEMYuV2DOlgk88JxKx..."],
    nonce: '0x' + nonce
};

//contract instance
const contractInstance = simpleContract.new(123, contractData, function(e, contract) {
    if (e) {
        console.log("err creating contract", e);
    } else {
        if (!contract.address) {
            console.log("Contract transaction send: TransactionHash: " + contract.transactionHash + " waiting to be mined...");
        } else {
            console.log("Contract mined! Address: " + contract.address);
            console.log(contract);
        }
    }
});

This could be maybe due to

1. The nodes arent synced, so you could restart the whole setup and check do the transactions.
2. Try to get the confirmations on the transactions done in the console.This code may help you

    web3.eth.sendSignedTransaction("0x" + transaction.serialize().toString('hex'), (_err, _res) => {
        if(_err){
            console.error("ERROR: ", _err);
        } else {
            console.log("success: ", _res);
        }
    }).on('confirmation', (confirmationNumber, receipt) => {
        console.log('=> confirmation: ' + confirmationNumber);
    })
    .on('transactionHash', hash => {       
       res.status(200).json({ Message : "success", Body : hash})
    })
    .on('receipt', receipt => {
        console.log('=> reciept');
        console.log(receipt);
    })
    .on('error', console.error);

});
