Reg One part of first name missed in SSN

Hi friends,I came to USA two days back and I got a issue with SSN… it will be great if any of our friends help me on this. My first name is " Arun Kumar" and last name is “Babu”. It’s correct in all places like passport,Visa,L1A petition and i94…

Today when I applied for SSN they said my name will be printed as “Arun Babu” because homeland security considered “kumar” as middle name. So slightly worried how to fix this,please let me know whether anyone can help me here
