Hi,
https://www.openstreetmap.org/node/4972855030/history doesn't appear to have any connection to the british chain you changed it to.

The official_name tag in https://www.openstreetmap.org/way/414033713/history looks more like an operator name?  official_name=* would be the full official name of the actual school.

What kind of clothes does https://www.openstreetmap.org/node/5529666651/history sell?  That's clearly not a clothes shop.  Same goes for https://www.openstreetmap.org/node/5529666663/history (which looks like it might not even still be in business - their website redirects to someone else and the sign appears painted over in bing streetside)

Your other edits look fine, but please be more careful and don't just automatically accept every suggestion the validator gives you.
