Urgent ! Surname space Issue in Interview ??

Hi all,
I have scheduled an interview for 10th Nov.
My name as per passport.
Given Name : Haris
Last Name : B C
But my I797B has name as :
BC Haris

Please note the SPACE DIFFERENCE of surname on my passport and I797B. I have filled DS-160 and all forms with name as per Passport [with SPACE in surname].
Will I have any issue with space in my surname while facing interview. Please please do help me !!!

Thank you.

There should be no issue. Usually Last Name is a single word in the USCIS system. For DS-160, go with what you have in passport and you should be fine
