No PVP Unit Frames in Arena

[nydac]

Hello, I recently started using nUI Plus and played in the Arena for the first time since I installed the UI. I can't seem to find the enemy PVP unit frames that, by default wow UI, show up on the upper right side of the screen when the event starts. The frames normally show enemy classes and hitpoints etc. (I'm sure you know) Am I missing something? Or do I have a plugin conflict of sorts?

So far I love the UI.

Thanks!
