Where is the new update?

When I open the Fruit Ninja app, there is a notification saying that FN has a new update, but when I click Update, it redirects me to the Fruit Ninja page on the App Store and there is no Update option, just Open. If there really isnt any update please fix the notification problem. If there is, please fix the update issue.
