I have the same update notification that keeps showing up every day, I want to deselect it once and for all.

In the past several days I've been getting an update notification for Harmattan Documentation. I don't need this doc and I do not have it installed on the first place. I click on Update, that gets me to the dialog box to select/deselect components I'd like to update, so I deselect it then I can only click Cancel. In a bit I get the same notification again. I want to get rid of the update notifications that I previously deselected.
