I CAN ID ONLY ONE APRIL TAG. WHAT AM I DOING WRONG.

I am attempting to use Tag Recognition on the Huskylens.  I aim the camera at an image containing multiple April Tags (an image on a computer screen).

The Huskeylens EASILY sees multiple April Tags in the image.  A square appears outside each tag and there is a cross-hairs at the middle of the Huskylens monitor.

I move the cross-hairs to one of the April Tags and press the “learn” button.  The Huskylens properly identifies that April Tag as “ID1”.

Here is my problem.  I expect the cross-hairs to reappear so I can move to a second April Tag and press the “learn” button to identify that tag as “ID2”, etc, etc, etc.

Instead after the first tag is learned, and I press the “learn” button to id a second tag, the display says “Click again to forget”.

WHAT AM I DOING WRONG ???!!!
