AR object getting but off by target object

I am using Vuforia to create an AR app. When I run the app either on iOS or via the webcam, I am able to see my object. The issue is unless I am about 5" from my target object, my AR object gets cut off. From what I can tell the AR object is going behind the target object instead of staying on the same plane as the target. I can upload a video if this explanation is confusing.
