Wwise Unity: Nested State/Switch states not playing in Unity?

Question

So i have a combat Music Hiearchy Set up: http://imgur.com/a/PVKRh
 

When Combat happens, i set the state to "Combat" Which has its path set to the shown Switch Group: http://imgur.com/6wPAYFo

This works beautifully in the Wwise editor, the transitions are flowing, and its organized in a understandable manner.

But it does not play in Unity. Other State's Songs play just fine, but when combat happens, it goes silent until "Combat_End" state is set, where i only hear the "Victory" Switch variation if i meet the conditions in-game.
Then it returns to play music just fine, other than combat music.

Is there some Restriction or setup i need to do in order to get nested switch groups to play in unity? Some soundbank setup maybe?
