If there s a mistake there s nothing that can be come on Wikipedia According to UNESCO there are only two World Heritage sites in Albania not four As far as UNESCO are concerned the Ohrid Lake is in the Former Yugoslav Republic of Macedonia I m sorry but Wikpedia s polices on verification mean that we must go with the UNESCO source This means that there is no room for quibbling over state boundaries on the article However you may wish to get in touch with UNESCO who may be able to provide you with an explanation Happy editing
