What is your source for the eircodes on the houses in Killyduff? You may not copy eircodes from the eircode finder onto OSM, because that data is not open and thus not compatible with the ODB license on OpenStreetMap. Unless you found them displayed on the individual houses/ gates/ fences or got them from the house owners/ residents (in that case, pls add `source:addr:postcode` to the houses), please delete them.
