I think you are confusing Stroke Play and C-T-T-H (Closest to the Hole) rounds.
Only two of the current courses are available for Stroke Play: Kiawah Island and Bethpage Black Course. The rest of the courses are Closest to the Hole challenges, which essentinally means they haven't completed mapping the courses yet, but they've taken what they have and made a challenge out of them, where you get one shot to get it as close to the hole as you probably already know.
