Why won't the status bar on my lock screen show icons?

[AC Question]

When I got my galaxy s5, notification icons would show up on the status bar when my phone was locked. Then my phone performed an auto update and those icons are no longer appearing on the lock screen. I've gone to the notifications setting and gotten a big white box to appear that can detail notifications, but that's not what I want. I also haven't seen seen a thread answer this exact question, so if one has, could you please post a link? And if not, then could someone help?
