Hi,
you have retagged a building to an equestrian centre (leisure=horse_riding). This was a bad idea, imho, because
1. you removed the building=* tag from the building and it is no longer rendered as a building
2. the equestrian centre is larger than the building, the area should cover the entire site of the equestrian centre, like here: https://www.openstreetmap.org/way/1293314373 (or map it as a node). Compare https://wiki.openstreetmap.org/wiki/Tag:leisure=horse_riding
