Where is the new update? – Fruit Ninja Classic Review

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 isn't any update please fix the notification problem. If there is, please fix the update issue.
