Hi,
You have retagged https://www.openstreetmap.org/way/271711015/history from a building to a riding centre. But on PDOK/Bing it looks like a building. In OSM every building should have a building tag, otherwise it is not rendered as a building on the maps. For specific building types there are different tags available, e.g. building=stable, building=riding_hall. building=barn, ...
I would recommend to create a separate object (area or node) for the riding centre "De Wolvenhoeve", e.g. like here: https://www.openstreetmap.org/way/703036885
