When save more than 25 attendees, the option of "List Attached for > 25 Attendees" is automatically checked, but "Application Error" pop up, here is the error message:
Unexpected System Error. Please try your action one more time. If you encounter the error again, please forward all information, including the events leading to the system error, to your Expense administrator.
