When the initial step is executed for vertex extremes, the 0-index vertex should be considered visited, and it should be colored as the leader in all selected categories. it looks like the number of vertices not yet visited is incorrect at this point, and vertex 0 remains as small, black (unvisited) vertex on the map.
