It used to show up for me twice also, you have to go back to where the old ticker used to be stored & delete the ticker from there, if you keep anything, it'll keep both tickers/icons on your signature.

To delete the old ticker click the symbol * in the upper right hand corner, blue bar, settings, message board, delete the ticker and then save. Let us know if you need any further assitance.
