Amex Corporate Card transaction is picking MISC expense type for all MCC / MIS codes

Summary:

Hello Experts,

All the Corporate card setups are in place.

We have configured the MCC code mapping rules to Credit card ( CC ) expense types.

CC expense types are in turn mapped to expense report expense types.

The same MCC on VISA transaction is pulling up the CC expense type correctly based on the mapping rules whereas Amex transactions are assigned to Miscellaneous expense type for all MCC & MIS codes.

Any idea on why this is happening or how to fix this issue please ?
