Unread stories disappeared & not showing in read stories either

amazing - yes, i see they all came back - thank you for your time BTW: is there any way for me to personalize so I do not even HAVE a MARK ALL AS READ button because if I hit it, it was definitely ACCIDENTAL and I do not use that button on the reg (I prefer (mark OLDER (or newer) stories read)

THANKS AGAIN FOR YOUR HELP AND EXPLANATION - I’ll be much more careful not to go near that button again!
