Hi Alex, welcome to OpenStreetMap and thank you for your updates to the map. Note that the Mount Albert Aquatic Centre was already mapped as a building at https://www.openstreetmap.org/way/60846989 . Because it already exists as a building, it is not necessary to add it as a node. This concept is called "one feature, one OSM element": https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element

Cheers
