The purchase history is missing because the BCH in question wasn’t “purchased”. It was created automatically because I owned BTC at the time the BCH hard fork occurred.

Unsure how to proceed…

Hi, you can create a manual deposit transaction for that BCH and tag it as airdrop. Usually Coinbase provides this data so I would suggest deleting and re-adding the wallet just in case.
