I can't get the image to be recognized - Augmented Reality

Hi everyone, good afternoon!

I want to recognize several images and give me the friendly name of the image that the camera is seeing, I have these problems:

1.- I recognize image 1, Is tracked: “True”, get friendly name: “1”, I stop seeing image 1, Is tracked: “false”, get friendly name: “1”

I recognize image 2, Is tracked: “True”, get friendly name: “2”, I stop seeing image 2, Is tracked: “false”, get friendly name: “2”

I see image 1 again, Is tracked: “False”, get friendly name: “2”, does not allow me to recognize image 1 again.
