My model is always present in Play Mode

I have a problem in Play mode when testing Vuforia with a web cam. When I hit play, my model is already visible in the top of the screen. It is like it is getting picked up by the AR Camera before the camera detects the Emulator test target image that comes with Vuforia. This makes it very hard to detect the test target image. This happens whenever I place any object that is big enough to "block" the AR camera's field of view. I would think with the object being a child of the Ground Plan it would be hidden until the target is detected.

Any help would be appreciated. I can't be the only one having this problem this is a very basic setup just an AR Camera, Plane Finder and Ground Plane Stage.
