Credit Card Previous Enquiries affecting my Current Applications?

I am new to credit cards (only holding one DBS Credit Card), and have been working for about 6 months. How do I erase my previous credit card enquiries? I previously applied for CIMB credit cards (about 3 times), and they failed because of administrative reasons: I failed to attach required files during the applications. However, these 3 attempts counted as CIMB REJECTING my credit card applications. This record has tarnished my ability to apply for more credit cards (e.g: rejected by Citibank)
