White Squares on Status Bar

I've got a Moto X Developer Edition with Lollipop 5.1 on it. I love everything about it except for the fact that some of my app notifications show up as white squares on my status bar instead of the regular app icon which used to show up for me on status bar when I had KitKat. I had been told that this only happens with apps that haven't been optimized for Lollipop. I was willing to accept this until I got Lollipop on my Samsung Galaxy Tab 4 8.0 a few weeks ago. I noticed on the tablet that all of the appropriate app icons show up as normal on my tablet whereas the same notification on my Moto X shows up as just a plain white square. I then have to swipe down for my notifications to see which one it is and read it. Is there something that I'm missing in Motorola that will help me fix this issue?

I've got this a lot on two apps in particular. One of them is the 14News app (local news app in my area) and the other one is NASCAR Mobile.

Any help I can get on this would be very greatly appreciated.
