Hi,
Why did you tag https://www.openstreetmap.org/way/1167974993 leisure=pitch + sport=equestrian (= riding arena) and https://www.openstreetmap.org/way/1167974995 leisure=horse_riding (riding centre)? I would have tagged both as arenas (leisure=pitch + sport=equestrian), and also these older ones:
