Cant find issue-transaction of Coinbase "missing purchase history"

Describe the problem:

Wallet: Coinbase (Coinbase)
Transactions: 282
Imported with: API
Troubleshooting before tax report: 1 transactions are missing purchase history

Koinly indicates there is above issue.
I can’t find that issue in the transactions overview.

What have you tried to fix this so far?
All of the blue-green buttons on the right show 0 results, and same for the “Warnings” filters.

How can I find the transaction that Koinly says is problematic?
