Hi,
https://www.openstreetmap.org/way/1265439310 seems to be a riding arena. In OSM these are usually tagged like pitches and not sports_centres (example: https://www.openstreetmap.org/way/1109822593). Alsoi it does not make so much sense to map one sports_centre inside of another. See also https://wiki.openstreetmap.org/wiki/Tag:leisure=pitch#Examples
