485 transferred 3 times

Sorry for posting it a second time.I am very worried now but no one answered my question this afternoon. My I-485 has been transferred 3 times already. I am so confused righ now. Can any one please help me figure it out? many thanks in advance.

Background:
My hu*****and and I filed I-485 the same time, concurrently with I-140. his I-140 and I-485 were approved in August and October 2004 respectively in San Francisco, CA. For working reason, I live in North Carolina.

Now my case was again transferred from San Francisco to AAA city. but initially it said AAA city INS office does not have jurisdiction right over my case. so why the case was transferred to them ? Could anyone offer help? what should I do now? does it mean my case was approved at San Francisco and if I pass the AAA city interview(background check, valid marriage, etc), then I will get my greencard? Many thanks in advance.
