credit card types

when needing a report of transactions, in particular online ordering, i export to a pdf and print. The problem is on that report there is a column that says 'credit card type', but the type is not listed. the column is blank. It would be very helpful if the credit card type was listed so I know which transactions are AMEX or MC, VISA, & Discover. Instead I have to open up each transaction separately to see what type card is used. This is very time consuming.
