HuskeyLens Object Tracking

I want my robot to be able follow an object, so I have chosen a shape that is easy to recognize, and the Huskylens with Object Tracking enabled. 

I put Huskylens to Object Tracking and enabled Lean Enable, then I press down the training button and the yellow box pops up on the screen. I move my object around and Huskylens detects it drawing a yellow box around it (when tracking), and sometimes a blue box (when learning). 

When I think its learnt the shape I stop pressing the training button. 

I continue to move the object around the screen to finalize learning. 

Then I turn off Learn Enable, and turn off auto save. 

Now I sometimes get a yellow box drawn on the screen and it tracks the object, but other times there is no yellow box, and it is not tracking anything. 

My question is …

After training an object tracking network, and then disabling learning, is Huckylens supposed to draw a yellow rectangle on the screen as its looking for the object ? Or does it never draw the yellow rectangle unless its in learn enabled ?
