3812847 - Why is the Expense Type from my transaction related to Airline auto-changing to Airline Fees when moving the transaction to a report?

I have a credit card transaction that is properly mapped on the Merchant Code Mapping.
On the user's available expenses, this expense type is properly Mapped as well.
Therefore, when I move the transaction to an expense report, the expense type is auto-changing to Airfare Fees, Flight Fees or related.
Why is this occurring?
