Welcome to OpenStreetMap and thanks for contributing.

Where you have the individual pitches of Watford (Cassiobury) Croquet Club, these don't really need name=* tags, as they're enclosed by another polygon representing the whole club,
https://www.openstreetmap.org/way/1073959280

The enclosing polygon should was incorrectly tagged by another mapper as leisure=pitch and should actually be leisure=sports_centre + club=sport

See https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dsports_centre

This is only a minor issue and there isn't anything in your edit which would be likely to cause problems for data consumers.
