Since it's from your blockchain(dot)com wallet's "Trading Account", those transactions are generated by their system and it's custodial.
I'm afraid that it's only their customer support that can solve the issue.

Note: Only your 'Trading account' is custodial, your 'Private Key Wallet' and other accounts that you've created in the settings are non-custodial.
