The clock on my Always On Display changed itself to a 24 hour clock from the 12 hour. I'm pretty sure I didn't do anything, though I guess I must have. But when I go into clock style to try to fix it, I get an error saying "Seems that you have hidden all the apps from the list. To restore them, go to Settings." But, I don't know what that means or hwo to fix it (before I can fix the clock). I tried a restart. Thank you for assistance.
