solidity – Troubleshooting Random Words with Chainlink VRF v2 Not Working as Expected

I am using ChainLink VRF V2 – DIRECT FUNDING METHOD for getting a random number.

Source code

https://remix.ethereum.org/#url=https://docs.chain.link/samples/VRF/VRFv2DirectFundingConsumer.sol&optimize=false&runs=200&evmVersion=null&version=soljson-v0.8.7+commit.e28d00a7.js

When I use the function requestRandomWords it is returning only one random word. The uint32 numWords = 2; configuration should return 2 random words but returns only one.

lastRequestId shows only one id. Cross checked requestIds too but generates only one.

Let me know where am going wrong.
