Fixed Deposit balance not matching with Bank - Audit

Hi, so this is the first year of audit taken up by us. The previous auditor did not check correctly and did a poor job of verifying the closing balance with the bank and it does not match with the bank. He was asked to resign due to his poor work and we were appointed in his place. Accordingly, our issue is actually from the opening balance which does not match with bank balance. We found this at the end of audit and now we want to know whether to modify our opinion. 

Our current year interest computation and TDS is matching correctly with bank.
