app tray keeps deleting folders

[monsieurms]

I organize by subject--like ebooks. I look the next day and many apps placed in neat folders are on their own again.I thought updates might do that, but programs not affected by updates are stripped out of the folders, too. Thoughts?

Note: NO folders create on home screens or the like suffer this problem. ONLY in the app tray.

Sorry, rookie mistake.

Galaxy Note 4, using only Samsung's interface, no launchers.
