I have revised the text file by manual as attached.
Please kindly check and advise us if it is ok.
For this mistake , I think maybe it is caused by digit of PO number. Actually, it will be shown XXXX-XX-XX (10 digits) but the both of PO.58-01-16 and 59-01-16 have 8 digits.
However, I will check my IT team and will advise you tomorrow.
Sorry for any inconvenience.
