Incorrect token type returned

It seems like there is an issue with type on some tokens.

Given this call https://api.covalenthq.com/v1/42/address/0x70997970C51812dc3A010C7d01b50e0d17dc79C8/balances_v2/?quote-currency=USD&format=JSON&nft=true&no-nft-fetch=false&key=

A token is returned that shows "type" : "nft" but does not show anything other than ERC20 in supports_erc . Any ideas on what is going on here?

To add extra info.

I dug a bit deeper and realize that, perhaps, the issue is not that “type” is wrong, but perhaps the “supports_erc” is wrong.
How was the type determined? It just seems to be a mismatch…
