I-765 Receipt number not Received sent along with I-485 Packet

[RAUSA]

October 1st week, I sent my EB1 AOS package containing I-485, I131 and I-765 and on October 3rd week received receipt number (NOA) for I-485 and I-131 but not for I-765. Do I have to resubmit my I-765 application again or should I wait more to see whether I-765 receipt number getting generated or not?

Maybe a combined card?
