Mint on Deploy; Etherscan showing 2 holders

Smart Contracts

I am working on a contract which will Mint 100 NFTs to a wallet upon deploy. I am trying to understand why Etherscan is showing address(0) as a Holder.

Constructor:

    constructor(
        string memory _name,
        string memory _symbol,
        string memory _contractURI,
        string memory _initBaseURI,
        string memory _initNotRevealedURI
    ) ERC721(_name, _symbol) PaymentSplitter(addressList, shareList) {
        setContractURI(_contractURI);
        setBaseURI(_initBaseURI);
        setNotRevealedURI(_initNotRevealedURI);
        _mintNFT(marketingWallet, 100);
    }

Mint function:

    /**
     * @dev Internal mint function
     */
    function _mintNFT(address _to, uint16 _mintAmount) private {
        addressMints[_to] += _mintAmount;
        for (uint256 i = 0; i < _mintAmount; i++) {
            _safeMint(_to, _getTokenToBeMinted(totalMinted()));
            _totalMintSupply++;
        }
    }

I would recommend showing your complete contract, to know why when you mint your 100 nft, the contract burns 100 more
