H1B Extension status changed from RFE to "Case was Received"


I have applied for my H1B extension and document has been received by USCIS on On June 10, 2016.

I have received the receipt # LINXXXXXXX (i assume it as Nebraska Processing Center) and went into RFE on July 13, 2016. I have submitted the required documents on Aug 08, 2016 and i am assuming that USCIS might have received with in a week, But now after RFE, my status has been changed to “Case was received” “On June 10, 2016, we received your Form I-539…”.

So i am confused with my current status, could someone please help me?

Has anyone went into this situation?
