Received status ?Card/ Document Production? update before oath ceremony

[cth]

Hello,

I?m expecting my oath ceremony at courthouse in a week in Atlanta. However, today I received a status update to ?Card/ Document Production? and stating that ?On May 11, 2017, the Post Office delivered your new card for Receipt Number EACxxxxxx, to the address that you gave us. I have received my oath ceremony but nothing else. Any idea what this update means?

Thank you,
