We do not tag for the renderer, especially not for the standard view (OSM Carto), see https://wiki.openstreetmap.org/wiki/Tagging_for_the_renderer

I've changed the individual pitches, they now show up nicely on OpenCampingMap, see here: https://opencampingmap.org/en/relation/15973307#18/36.10122/-112.09656/0/1/e6f
