Hi,
why did you retag https://www.openstreetmap.org/way/1069695518 from pitch to horse_riding? It is riding arena and not a riding centre. In OSM riding arenas are tagged leisure=pitch + sport=equestrian, see https://wiki.openstreetmap.org/wiki/How_to_map_a#Riding_centre_(equestrian) . Also it makes no sense to have a small riding centre mapped inside of a larger one (https://www.openstreetmap.org/way/1159491930).
