No New Caledonia on the ‘countries visited’ map

I just want to make a request to the Jetpunk Quizmaster, about the absence of New Caledonia on the ‘countries visited’ map. I have been to New Caledonia, many major nations can be ticked for their internal first-level subdivisions, so can France. But when I saw the regions, I realised that New Caledonia was missing, I don’t know if this is deliberate or an accident, if it is deliberate then can you tell me why? If it is because it has some sort of autonomy compared to other French territories (other French overseas territories such as Mayotte, Martinique and French Guiana are all present as a box to tick), maybe New Caledonia could be included as a subdivision of France? If it has some degree of autonomy maybe it could be put in brackets just like (greenland)/(palestine)?
