Hey, thanks for adding to OSM. Unfortunately the holes itself are not completely correct. https://www.openstreetmap.org/way/1364135946 and https://www.openstreetmap.org/way/1364135947 should not be used for an individual hole for the disc golf course. 

Check https://wiki.openstreetmap.org/wiki/Tag:leisure%3Ddisc_golf_course and just ask if you need further help (also possible in chat where we talked aready )
