Reality Composer Image Target Instability

Is anyone else having trouble with image targets in reality composer? When I move my phone directly over or in very close proximity to an image target, my scene shows correctly. But as soon as I move my camera away the scene seems to jump to some arbitrary location in the room. When I move back to the target it comes back to the correct location shortly.

any headway on this issue? I have the same problem...
