Help! i received I-485 interview notice while we still waiting on petitioner's FP notice?

I have filed I-485 and I 130 concurrently in july( with EAD application and advance parole ). we never recieved biometrics notice. I ( applicant) went up to local immigration office 2 weeks ago because I never recieved my EAD after 90days of recieved date. and on the same day they sent me to application center and got my FP taken. but my husband (petitioner) never got his finger print taken yet. Today i have recieved the interview date in the mail. Isnt he supposed to get Finger print taken before interview???
