Hi,
https://www.openstreetmap.org/way/1371333129 and https://www.openstreetmap.org/way/1371883625 are no horse riding centres (leisure=horse_riding); they are horse riding arenas which should be tagged with leisure=pitch + sport=equestrian. See https://wiki.openstreetmap.org/wiki/How_to_map_a#Riding_centre_(equestrian) and https://www.openstreetmap.org/way/854844204#map=19/51.451222/4.472089&layers=P (example)
