Hi Dean! Sorry to hear that the cone shifted a bit! If you press it down about as far as it's held down when in place on the guitar, is the cone still making contact with the case? If it's not, it should be fine. You do have the option of simply peeling that cone off and centering it in place! Peel from one edge rather than attempting to pull the cone off all at once. It's got adhesive on the bottom of it so it'll stick back in place.
