Hi,
you have removed building=yes from https://www.openstreetmap.org/way/1361161344 although this is probably a building. You have added leisure=horse_riding to it instead although this tag is not for buildings but for complete riding centres; maybe you should move this tag to https://www.openstreetmap.org/way/296536235, compare
