3816552 - Why the user is getting the error "This Expense Cannot Be Submitted Until It Is Matched To An Imported Card Transaction" when submitting an Expense Report?

Can you tell me why a user received the following error when they tried submitting their report, 'This expense cannot be submitted until it is matched to an imported card transaction. If this was not paid for via card, you may edit the payment type of the expense to reflect the actual payment method.' How do we resolve this?
