If it wobbles replace the wax ring at a minimum.
You can fix the wobble by caulking on both sides or front/back depending how the wobble is.
A popular theory is that it shouldn’t be caulked or sealed, and if you do, don’t seal it completely.
Rubber seals (instead of wax) can tolerate some wobble, but they might harden, crack and leak later on due to age if there is a continuous wobble.
