Hi Bobbili_Puli,
USCIS has implemented the bi-partisan law through e-filing too. If your current address falls in NSC region the webapp makes sure your application is sent to NSC. This is a recent change. I couple months back I efiled for EAD and it went to TSC and recently e-filed for my wife, now it went to NSC.
I don't think there is anything wrong here. Just send your docs to NSC.
