H1b Extension filed and traveled outside US. Visa and i94 expired


My VISA and i94 were expiring on 4 April 2018. I traveled to India on 28 March after filing the extension and getting the receipt number, Case was upgraded to premium. RFE received on April 17. RFE replied on June 16.

IN RFE they asked only one document i.e. BRM letter explaining job duties.

Extension denied on July 02. Can you please suggest if travelling outside USA was reason for denial?
