publishing installs, can't select “android only” audience for ads?

Seems I failed to mention anywhere, but this is for Facebook ad campaign, and Facebook install publishing.

I am unable to select “Android only” when trying to create my audience for app installs, the radio button is disabled, see image below:

I’m using CoronaSDK for creating a game, and i publish the install when the game launches. I have all of the information setup in the App Information page (package name, class name, key hashes are all filled out).

Any idea what could be keeping me from selecting “Android only” as part of my audience? Is there perhaps something I have to specifically for android?

You need to use the power editor for Android campaigns.
