The elements all have a "little" movement in them. However, if the movement is excessive in your opinion, i.e. if you just shake the whole unit and the wire moves, your idea of using some thin wire to shim it sounds reasonable to me. I do know that some pre-production units exhibited this concern and the factory was supposed to adjust the riveting mechanism to tighten them.
I checked the several production units I have here at the office and they all seem snug enough. Perhaps it was a one off occurrence.... We'll keep an eye out for it.
