Go Back In Time - different charge type (MCC code)

Warning about going back in time!
I recently used the Go Back In Time in time feature to change a transaction from a credit card to a debit card. I did this because the credit card saw the transaction as a CASH ADVANCE/MONEY TRANSFER and charged a fee accordingly. Seeing this on my card, I used Go Back In Time to change it to a debit card.
Curve applied the refund to the credit card, but it shows as a refunded PURCHASE, which is different to the original transaction. This has resulted in the original cash advance fee remaining on the card, as although the original charge and refund amounts were the same, the transactions did not match. Additionally, I ended up with negative loyalty points, as the original charge did not qualify for points, but the refund did - totally unfair!
