Different Identity!
The moment you apply I-485, you , spouse and kids ( if any) gets individual idenity. Everything onwards is on individual basis.
Forget FP doing to-gether on one FP, they even will not talk to you about your case if your spouse is not present near to you.
Wait.. you will get FP for your spouse also very soon.
BTW : What is code number written on FP , is it biometrics or FP notice ?
