3825018 - Why is Cash Advance (created via Request) have a different amount than the Cash Advance entry in the request?

For our Request Cash Advance policy, we have enabled Cash Advance Auto Generated Expense Type and the Expense Type "Cash Advance" is not enabled under "Expense Types". So the Cash Advance amount should always match the Cash Advance entry amount in the request. However, we recently noticed a discrepancy where the Cash Advance amount does not match the Cash Advance entry amount. What may cause this behavior?
