AR Object stuck in front of camera

This question is kind of the opposite of this (https://answers.unity.com/questions/51853/i-want-to-fix-an-object-place-in-front-of-the-came.html)

I am having an issue where my object is ALWAYS in front of the camera no matter where I move. I use a boolean so that once the object position is set, it doesn't get reset. But that doesn't seem to matter. As I walk around the room, the object is always in the same spot on the screen.

The AR object (just a cube at this point) is not a child of any other object. I have my main camera as a child of a 'player' object.

Does anyone have an idea of why my AR object is behaving this way? And how to fix its position in space so that as the device moves, the object is fixed and therefore sometimes on screen and sometimes not?
