Recently Listed NFTs aren't showing up

[crypto-caesar]

On Lesson 15, I have successfully minted an NFT on the Goerli testnet. I have finished everything with the lesson up through deploying the subgraph. I can find the contract address and see the NFT item listed as a transaction (https://goerli.etherscan.io/address/0x2e15A918e9B92ee879C93DD32F2105721a55f4cE).

When I tried querying The Graph using the same line given by Patrick, nothing showed up in the data section for the blank 0x00000000 address. The default query without the "buyer: "0x00000000"" section DID produce data.

So on the final step where this should show under "recently listed" in my website's UI, no NFT is shown, and nothing shows up in the page "/graphExample" under console -> objects.

The final part of my question involves styling. The code for my Header.js is a little different because it seems that Patrick used an older version, and now the < a > lines aren't necessary. I've been having trouble getting the UI to format to look similar to the video, below is what it currently looks like and my code for the Header.js:

import { ConnectButton } from "web3uikit"
import Link from "next/link"

export default function Header() {
    return (
        <nav className="p-5 border-b-2 flex flex-row justify-between items-center">
            <h1 className="py-4 px-4 font-bold text-3xl">NFT Marketplace</h1>
            <div className="flex flex-row items-center">
                <Link href="/" className="mr-4 p-6">
                    Home
                </Link>
                <Link href="sell-nft" className="mr-4 p-6">
                    Sell NFT
                </Link>
                <ConnectButton moralisAuth={false} />
            </div>
        </nav>
    )
}

@crypto-caesar The buyer's address is a full zero address, not just this 0x00000000. Check this LINK
