I485 LUD

Quitely strange, I did not receive any e-mail regarding to LUD of my I-485. But today when I happened to log on my case, the LUD has been changed from 01/10/2007 to 09/07/2007. The contents have not been changed at all. Is it normal?? What does it mean??

My case:
EB2 RIR --- NSC
LC RD: 02/11/2002
LC AD: 10/07/2006
I-140/I-485 RD: 12/08/2006
FP: 01/09/2007
I-140 AP: 07/09/2007
I-485 LUD: 01/09/2007, 01/10/2007, 09/07/2007
