Name difference in educational and obc certificates how to proceed

Dear Sir, I have a query related to my name difference in 10th and OBC, My actual name is YELLAPU SURYA PRABHAKAR RAO, My surname is YELLAPU, But in my 10th certificate it is printed as YELLAPUSURYA PRABHAKAR RAO with no space between surname and first name, and in OBC it is YELLAPU SURYA PRABHAKAR RAO, with space provided. Will it be a problem at the time of document verification or police verification, I am going to join in central govt. job. Actually i thought of changing my OBC as per 10th but the revenue officers told for OBC their will see SURNAME whether it is in COMMUNITY, CASTE LIST or not. My surname YELLAPU is in GAVARA CASTE and it is in OBC CENTRAL LIST, if i change my OBC as per 10th certificate a new surname YELLAPUSURYA will form which is not in GAVARA CASTE in OBC CENTRAL LIST. what to do sir??
