Hi,
https://www.openstreetmap.org/way/1280195200 is not a riding center, it is just a riding arena and therefore should be tagged leisure=pitch + sport=equestrian. In iD there is a different preset for riding arenas that sets these tags. Compare https://www.openstreetmap.org/way/707965571 and https://wiki.openstreetmap.org/wiki/How_to_map_a#Riding_centre_(equestrian)
