Hi,
The areas that you have tagged as horseback riding centers (leisure=horse_riding) don't look like horseback riding centers. They look like outdoor riding arenas or round pens and these are usually tagged differently (compare https://wiki.openstreetmap.org/wiki/How_to_map_a#Riding_centre_(equestrian)). This concerns:

Here is an example of a correctly mapped riding centre with a riding arena:
