What I did know is that some one changed his name by calling USCIS. For my experience, I did call USCIS to change my EAD three years ago. At that time, the officer also suggested me to apply for new EAD. I did apply for EAD again. So both way worked for me.So, I suggested you call them again. If I have a further information, I will let you know. Good luck
