Random String Appears After Token Symbol on Opensea

Question

I can't figure out why I'm getting this odd string after the Token symbol on Opensea with this NFT that I minted. The smart contract is below.

pragma solidity ^0.8.0;

import "@openzeppelin/contracts/token/ERC721/extensions/ERC721URIStorage.sol";

contract RizerNonRandom is ERC721URIStorage {
    uint256 public tokenCounter;
    constructor () public ERC721 ("RizerSeq", "RZRI"){
        tokenCounter = 0;
    }

    function createRizerNonRandom(string memory tokenURI) public returns (uint256) {
        uint256 newItemId = tokenCounter;
        _safeMint(msg.sender, newItemId);
        _setTokenURI(newItemId, tokenURI);
        tokenCounter = tokenCounter + 1;
        return newItemId;
    }
}

And here is what it looks like on Opensea.

Answer 1

This is taken from the token's metadata. You need to call tokenURI on your token, and see what the metadata that is being returned. OpenSea grabs the collection name and token name from there.

So the issue is with the "tokenURI" you supplied to createRizerNonRandom.
