The Basket contract is intended to be used behind a proxy. But the ERC721 implementation used is not upgradeable, and its constructor is called at deployment time on the implementation. So all proxies will have a void name and symbol, breaking all potential integrations and listings.
ERC721("NFT Basket", "NFTB") is called at deployment time, and sets private variable at the implementation level. Therefore when loading the code during delegateCall, these variables will not be initialized.
The easiest mitigation would be to pass this variable as immutable so they are hardcoded in the implementation byte code.
