Issues with Create expenses from email receipts

Issues with Create expenses from email receipts

1. Emailed one receipt for airfare expense to Oracle , and it created two expense items, basically it duplicated the expense item based on Arrival and departure dates. 
Expectation was to create one expense item with the total amount. Is there a way to fix or teach the IDR?

2. Sometimes it does create the expense item in Oracle from the email receipt but sends back 2 email notifications, one saying expense successfully created/ FYI: Your Expense for 10.00 USD Was Created and other one saying expense not created/ Attention: Can't Process Your Receipt. 
This will cause confusions. Is there a way to fix this?
