140 online updated again

My I-140 has been approved in May. and I sent out the 485 package 2 weeks ago, but I haven't received the receipt notice. Today, I found on the USCIS website, my I-140 case was updated again, though information in it is not changed. It's kind of strange. It does mean that they access my case again after approval. Does anyone else encounter the same thing?
