If the swirl mark remover is leaving light scratches you can try using it again, only this time use a damp (not wet) soft cloth. Start rubbing the entire surface with mild pressure. After you've gone over entire surface, go over the surface again, only this time use just a little pressure. Use a clean, soft, dry cloth to finish. When done apply a coat of furniture or auto wax, apply with clean damp cloth using light pressure. If this doesn't work then try the compounds referenced in last post.
As to whether finished correctly, it's possible but hard to tell. A more common mistake is applying a durable finish over a sift finish, but in that situation you don't really see 'scratches', but instead you see 'dents' - sorta like being able to leave a mark if you push a finger nail into the finish
