Items don’t delete

Items are not deleting!!!  I delete an item close the app and when I go back and reopen the app the item I deleted is still there!!!!  This also happens with repeating items.  I click it that it’s done and it resets for the next week.  I close the app and when I go back the item is red and is not reset for next week.  Oh, and I add an item and when I go back the item I added is not there.  

How can you have all these glitches???  I’ve been using your app for years.  I love it.  I tried looking for another app but I haven’t found one as good as yours.  These glitches shouldn’t be happening all the time.
