Why does REST API Create an expense record not allow value CORP_CARD" to field ExpenseSource

The following paylaoad execution was carried out with the objective of inserting an Expense report with an expense item where its "Expense Source" is CORP_CARD.

The payload response was successful; However, we observe that the Expense Source field has the value CASH. The rest api did not take the value of CORP_CARD

What value should we enter so that the item is of type Card?
