Notification updates not reflecting in the alert

Also clear all notifications using trash can icon does not result in any notifications being deleted in the app.  If I individually delete some notifications (or do nothing), the alert maintains the prior list (for days and days).  If I individually delete all my notifications in the app, the next time the Android alert pops up it shows the new notifications, but then continues to show the same list of story headlines each time the alert pops up until I again manually clear the notification list in the app.  This has been ongoing for over a month.
