I suggest posting your savegame for this. It might be a bit into the game where the trainer maker didn't have time to go when he made the trainer.
Please use the trainer option request system for requesting new options be added to this trainer and/or vote on options already requested.
toggle the option on, then while on map, place a waypoint. DO NOT CLICK ON A AN ICON, you need to place a waypoint NEAR it, not ON it.
