First, kindly identify what are the incorrect values. If the front zeroes are missing, it could be because you opened the bank file in an excel file which will remove the preceding zeroes. Try opening the file in a notepad and check if the values are still incorrect.
If the values are still wrong, change the bank information for the affected under ePayroll > Payroll Admin > Employee Pay Details > Human Icon
After that is done, regenerate the bank file once again under ePayroll > File Generation > Bank.
