hi, welcome to OpenStreetMap (OSM) and thanks for editing. 

There is already an existing node for Slavic Village so I have deleted your node. 
(https://www.openstreetmap.org/node/153932723) 

In OSM, we only map things once (https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element); otherwise, it would be pretty confusing to have 2 slavic villages :D 

if you have any questions about OSM, feel free to contact me. 

regards,
will in cleveland

ps: i'm familiar with your organization and you do great work!
