I am using a good quality black-and-white image target that tracks very well. However, an inverted version of the image (black and white parts reversed) will not track.
The attached images show the features of both images are the same. Should I add both targets to my application if I want to track positive and negative versions of the same target?

Yes, it should not work. Inverted image means changing descriptors, so no match is expected. I've found an explanation for how this works in SIFT, but in principle it's the same issue for Vuforia: https://stackoverflow.com/a/15044609
