Vuforia Target Image scene not appearing in game

I am attempting to create a plane using target images. The plane is visible in my scene. However, when I press play the camera detects the image targets however nothing is overlaid. The plane is not visible in the camera screen. See photo attached. How do i make the plane appear over the target images?

Please note: I have tested the scene with all of the target images, my screenshot only shows two because thats the only way i could take a photo.
