Does USCIS site shows wrong status

My H1B status in USCIS website shows the current status as “Response To USCIS’ Request For Evidence Was Received”

but I received i797b from my employer 20 days back. Does that mean RFE resposne is getting reviewed again?

Is there a possibility that USCIS shows wrong status? Is there a possibility that RFE gets reviewed post the pettition approval
