Rotating platform teleport puzzle: platforms aren't rotating

even “funnier” when i teleport into the room, my characters is constantly spinning around even though the platform is not moving. when i try to go into the nearest teleport ball i do not go up to the higher level platforms.

this picture is from a video walkthrough i was using to figure out what was wrong. i am not having any luck actually taking a real in game screenshot right now.
