OFC appointment letter question, Please help.

[gagarp]

I booked my parents appointment by adding mother's information as a "Add Dependent". When I print the appointment letter, I got bar code for both mother and father(both bar code incl. ds160 & fee). Total of 4 bar codes, I can see. 

 

Now on appointment letter in very first section there is ONLY my father's name , PP# & applicants = 2 written
and NO mother's name but I can see bar codes for both of them.


Please let me know if this is correct for appointment... 

 

Thank you,
