I am unable to submit an expense (airfare) because it is listed as "Pending Card Transaction."

Two error messages show for this:

• "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."
• "Action: Only Corporate Card Expense transactions may be on a T&E report. Please remove any non-Corporate Card transactions and add them to the correct report type."

I do not see the airfare transaction listed in my "card transactions" list in Concur.

How do I fix this issue?
