ArActivity Objects goes away from the screen and disappears on swipe

[dhagz]

I was following this video: https://www.youtube.com/watch?v=r10C1Wn2SGM
And instead of using the DefaultARSetup I am using the DebugSetup.
Now when the ArActivity starts up, the Objects slowly gets away from the screen, when it's totally out of the screen I could not see it even if I point the camera to different directions.

I started the ArActivity again, then swipes the screen, the Objects disappears.

Any thoughts?
