Keyboard Layers not displaying

I recently upgrade to Mainstage 3 and found that when I open the concert I was previously using with Mainstage 2, any new instrument channel strips will not display keyboard layers in the Edit or Perform window.

The layers are however showing up in the Layer Editor below the Workspace and can be edited. I can hear everything fine and they play as normal but not being able to see them displayed on the Perform screen is kind of annoying.

I should also mention that "display keyboard layers" is checked in the Layout screen up to a height of 3 levels so that is not the issue. Also, when I open a brand new concert template I can see the layers in every window as expected when a instrument new channel strip is added. It seems to be a problem with my old Mainstage 2 concert.

Figured it was a bug and I can't find any mention of it in the forums. Any suggestions would be greatly appreciated.

I am running Mainstage 3.0.3 on a Macbook Pro with Mavericks 10.9.3.

Thanks very much!
