I485 approved or not?

I received two denial letters today from TSC regarding my
I131. One says that it's because that my I485 was approved;
the other (dated one day later) says that it's because that
I applied too early. Both are from the same director. I check
the website and find no updating of my I485 case (EB1b,10/2004).
Can XIAOBAITU or any one with experience tell me what's going on? Many thanks!!!
