Zapworks Studio multiple tracking of images(Simultaneously)

I am building a project where I am working on 2 cards(markers) for eg,
I have checked the multiple tracing solutions on the server but it is not simultaneously tracking those 2 cards. Individually multiple tracking is there but when I bring in the two cards together it’s either scanning one of them or the other. How to achieve simultaneous tracking of more than one marker in the scene.?
I checked this link for multiple tracking done by @ jvouillon.
Please help me in this issue urgently.
