Twice now when I try to use my grocery list to check off items for my shopping list it disappears. Why? Is Samsung deleting list after a certain period of time. I use this grocery list to create my shopping list for many years now. I go down the list of grocery items click on them and they pop into the shopping list. Now they're all gone and I have to type in the new grocery items to populate the shopping list. It is now retaining those items but I have to rebuild my list all over again. Why
