c# – Multiple Model Target identification and tracking possibility with Vuforia?

I am trying to identify and track 2 different objects using model target in Vuforia (10.15.3). Is this possible with Vuforia (either free or premium version) ? With 2 model target and 2 different datasets, Vuforia is identifying only the first dataset and I am getting a console error :” Exception in callback: Failed to activate observer for Behaviour {second dataset name}”. Is this an error due to my mistake in configuration or this feature is not supported in Vuforia? Any help is appreciated. Please suggest if you have any other ideas to solve the issue as well.

As I created 2 different dataset and model target; each model target mapped with different dataset, only the first dataset is identified and tracking. I am not even receiving a guide for dataset 2. I have tried to run both on windows with webcam and an android phone.
