The professional name displayed as a heading to a Name Page should be your name as you are most often, most recently credited on screen. So, if that is, "Daniel Pigliavento" and it was simply misspelled on screen, that can be noted. If it was correct on screen but just misspelled when input into IMDb, that will be fixed a different way.
Can you verify which was the case? If misspelled in the credits, your name heading should be changed but the credit on screen needs to be noted with "(as Daniel Piglavento)."
