It appears that you deleted a node which represented the same school that you added in this change-set. Elements should be deleted if they no longer or never existed. If the feature is already represented by an element, then it is good practice to modify it instead, because that preserves the metadata and history of the element. A positive is that I can tell which buildings in the imagery the nodes represent. The church looks like it's tagged correctly, other than the address.
