Hi, thanks for editing this place! I see you used StreetComplete for the edit? I'm surprised that it made the edit in 2 steps (version 4 and 5) and that it did not remove the linkswikipedia and wikidata tags of the old school (I corrected it, see https://www.openstreetmap.org/changeset/168149799 ). Can you please explain what you did, and how you added the website of the new school? Then I can report it to StreetComplete developers as a bug.
