No priority date for I-131 and I-765

[NSTJ18]

I filed twice because my case got rejected for the first time (except I-130).
When I received the receipts for the three forms, my I-485 PD stayed the same as my I-130 (07/2018), but the other two came blank in the space of the PD.
I have been waiting, and today I called USCIS, but the waiting time was too long.
Does anyone knows what it means or have anyone experienced that?
TIA

I don't think there's PD for 131 and 765 as you should look at "Received Date" in reference to the processing time.
