The school is already tagged on this area:
https://www.openstreetmap.org/way/1031575190
It shouldn’t be duplicated on the school building object, see:
https://wiki.openstreetmap.org/wiki/One_feature,_one_OSM_element
Please remove name and website from the building.

Unrelated, but consider using JOSM (a Java-based editor), while initially it may be more difficult, it won’t teach you some bad practices of iD (the web editor you made this changeset in).
