The Cumulus points received for a purchase are listed at the bottom of the receipt. There is a text error in the list.

"Cumulus number:" (OK)
"Points received:" (Only the points properly received are listed here.)
"Of which bonus points:" (Only the bonus points are listed here. The word "Of which" is incorrect. The points are listed aditively one below the other. Can send you a receipt on which this is visible).
