Solution

1. Follow the right process to create genesis file https://medium.com/xinfin/how-to-set-up-a-private-blockchain-network-with-xdc-network-codebase-b2ee82368e83, you can check the log like this, can see how many masternodes are configurated into genesis file as you want.

2. Key point is Epoch number must be 900 in the genesis file, due to lots of parameters are bind to Epoch 900.

    "XDPoS": {
      "period": 2,
      "epoch": 900,
      "reward": 10,
      "rewardCheckpoint": 900,
      "gap": 450,

The epoch mentioned in the genisis file is "epoch": 900,
