Upgradable contract generated from OZ wizard is not working as expected on mainnet

Hi there,

I've followed the wizard (https://wizard.openzeppelin.com/) generated the code and used the hardhat (upgrades.deployProxy) to deploy the generated upgradable ERC20 contract. It's working totally fine on Rinkeby and Kovan, but I tried to deploy it to mainnet, the _mint func in the constructor was not called as expected.

By the way, I've used the hardhat to verify that contract on etherscan without any issue, but nothing returned from name/symbol/totalSupply functions.

any thoughts why this happened? thanks
