Reality Composer bug(?) when target not present

Is anyone else having trouble with image targets in reality composer? The detection itself works fine, properly showing my intended .usdz file when the target is seen in the camera view. However when the target is not seen or when the camera is pushed up close to the target, the AR object is shown at an arbitrary location when it should be hidden. Any help is welcome. Thank you very much.
