Hi,
Can you please map just one object for every horse riding centre instead of many? Here you have mapped 5 areas with this tag which probably belong to one horse riding centre:

https://www.openstreetmap.org/way/1309499677
https://www.openstreetmap.org/way/1309499678
https://www.openstreetmap.org/way/1309499679
https://www.openstreetmap.org/way/1309499680
Compare https://wiki.openstreetmap.org/wiki/Tag:leisure=horse_riding#When_not_to_use . Maybe you can add the horse_riding tag to https://www.openstreetmap.org/way/230089684 instead. Then the thing would look similar to https://www.openstreetmap.org/way/842780067
