Nexus 4 transparent navigation issue

I just installed Nova Launcher Beta so I can get the transparent navigation and notification bar. I love Nova Launcher Beta, but there is just one small issue... the navigation bar is not transparent.

I'm a little bit OCD about this. Every time I look at my home screen, its driving me crazy!

Did some of you guys encounter this issue after installing the beta? If some, how did you solve it. Any help would be appreciated.
