Remix IDE complains about `ERC721Creator.sol`

I was trying to use remix ide and import the the ERC721Creator.sol. I do this as follows:

import "@manifoldxyz/creator-core-solidity/contracts/ERC721Creator.sol";

Unfortunately, as soon as I add this to my file, the compiler complains that the function _beforeTokenTransfer at line 27 has an invalid override modifier. Any thoughts?

It’s a version issue, it works if you change the remix compiler to 0.8.0. Remix will always default to the latest compiler version which won’t always work with npm-published contracts.
