I am unable to delete a bank transaction as it says “The transaction has been categorized/matched” although the transaction’s status shows as manually added. How do I delete it?

To delete a bank transaction under such cases:

• Make sure the transaction has been categorised in another bank account. You can find this in the transaction’s description.
• Go to the respective bank/ cash account.
• Search for the transaction and click Unmatch / Uncategorise to remove it from the previous account as well.
