Welcome to OSM! Please have a look on  https://www.osm.org/way/1445898980. What is the mean of the tag "Plaza con sombra y juegos, pública- (CEMENTERIO VIEJO)" = "Malvinas Argentinas"? Did you overpaint a existing leisure=park? Did you see https://www.osm.org/way/108588564?

If you need help: You are welcome.
