Hi,
You have tagged https://www.openstreetmap.org/way/572278236 leisure=horse_riding (riding centre), but it is a building that belongs to https://www.openstreetmap.org/way/41435948 (Stal De Driegang) which is also tagged leisure=horse_riding (riding centre). Nested riding centres don't make much sense, compare https://wiki.openstreetmap.org/wiki/Tag:leisure%3Dhorse_riding . If the building is a riding hall / indoor arena you can use https://wiki.openstreetmap.org/wiki/Tag:building%3Driding_hall
