Payroll - P60's contain blank fields rather than 0

Hi

I have recently printed my P60's and unfortunately I have noticed that 6 of the fields have been left blank when they should include a 0 (zero).  

Total for year tax deducted field

Statutory Maternity/Paternity/Shared Paternity and Adoption Pay fields

Student Loan Deductions field

Whilst I know no payment has been made there should be a 0 entered to ensure the forms can not be changed/tampered with in anyway.  My previous payroll software automatically entered a 0 when no payment was made and incidentally a 0 has been entered into the "tax deducted in this employment" so why not the other fields?  have I set something up incorrectly - can anyone assist please?

Thanks
