I get a message "This update is not available for this Apple ID because it was bought by a different user or the item was refunded or cancelled."

I bought my Macbook pro a couple of days ago and it already shows me that I have to update some applications. (garage band, keynote, numbers, and pages) When I click on update it shows this message., " This update is not available for this apple id because it was bought by a..." I then click on "ok" and now the applications have an "open" button where the "update" button used to be. The only problem is that my App Store icon still shows the notifications on it reminding me that these applications still need to be updated. How can I properly update these applications?
