Nearest Neighbor - Severalneighbor where several vectors have exact same values

I'm trying to classify 6 dimensions-dimension feature vectors in two different classes using the nearest neighbor algorithm. After analyzing my training data, I realized that the same vector is present numerous times in both classes. What does this mean?

Does it indicate a bad feature choice?

or

During training, should I group identical vectors and label it with the class which has the highest count? (i.e. vector A is present in both class A and B, but label it class A since vector A is found more often in class A than in class B)

or

something else?
