That you own resale points has no bearing on your ability to make a reservation there. Some resorts were originally sold as deeded fixed/floating weeks and only a small number of owners may have converted their deeded ownership into points, so Club Wyndham may just have a small number of rooms available.
The Elysian (along with Bluebeards Beach Club) is one of those resorts. so it more just a function of the limited inventory owned by the Club, combined with those owners who have ARP at that resort.
