Hello,

Yes this was a mistake. Thanks for picling this up so quickly !

I looked at two other schools (https://www.openstreetmap.org/way/30499962 and https://www.openstreetmap.org/way/397937158 to get a clearer vision of how schools are defined before creating the school https://www.openstreetmap.org/way/177665619.

I have no idea why the first two were included in the changeset, that was not my intention.

If possible, it is probably best to revert my changes and I'll try again on https://www.openstreetmap.org/way/177665619, without touching the others.
