The clamp doesn't seem to be sitting "flush" on the seat rails in the pics. If the clamp is spread where it won't tighten on the rails, even if on all straight portion of the rails, you may need another post, as if the clamp has spread, trying to bend it back to where it would tighten may weaken it to where it won't hold good when tightened. Make sure the clamp is on the straight portion of the seat rails only, and not partially on a bend in the rails.
