Japan is the one I am adding, I wanted to add it so it is just like the others. So if Japan is not in the default namespace there, then I guess the question would be how I add it in correct one so it comes like the others.
Its same with me I cannot replicate the problem just by making other project.
The link you posted seems to hint that it adds it once. As far as I can see then the XML file that I am trying to add to does not have such node at top, maybe that is why it is trying to add it.
