Corporate card number format for Mastercard

Summary:

We're implementing Mastercard corporate card with masked card number format but the upload process doesn't show any transaction.

Content (please ensure you mask any confidential information):

After running the upload process with the setup for masked card number format, it's not possible to see any transaction. We change the setup and run the same process with the same file but for tokenized cards and now we're able to see all the transactions.

The log says "The uploaded file contains a transaction with a card number that doesn't match the card number format of the corporate card program. Contact your help desk" but recognized the transactions.
