Hi I successfully compiled and deployed my contract to the Ethereum mainnet using remix. I compiled with 8.0 and optimization disabled. With all settings correct and uploading all 10 solidity files to Etherscan (including the ones imported from OpenZeppelin) I’m running into multiple errors when verifying.
Here are the compiler warnings it lists:

Any suggestions would be appreciated and would be willing to pay someone to walk me through the entire process if they are familiar with verifying contracts that include multiple OpenZep imports, thanks.
