Does not update – The Week Number Review

The thing has the number on the icon but it does not update. I.e. I click on it, enter today's date (should be automatically) and the week number goes to the correct number. Hit the home button, and wallaa, the icon still shows the old week number. Change between US and ISO, still no update of icon. I uninstalled the thing.
