Why aren't my text message notifications scrolling on my notification bar?

Text messages notifications not scrolling in notificaton bar

I updated my Verizon M8 to lollipop and when I'm in an app and get a text it doesn't preview (scroll) the message in the notification bar. I'm pretty sure I've look at every setting to fix the proble, but I can't seem to find it.
