請問小白兔,辦EAD時CIS給了另一個A#怎麽辦?

My attorney filed 485 for me half year ago. Then, I filed EAD myself last month, I used I94# instead of A# to fill out the form (because I didn't know I got A# already when I received the 485 receipt. I just found out I have two A# now, one is on the 485 receipt, another one is on the 765 receipt, and they are different. Is the problem serious? Anything I can do to make it right? Thanks a lot!
