I am uploading my IRP5 file on easyfile and getting the validation error that 

Source code '3231' only permitted once per record.

Source code '3232' only permitted once per record.

Source code '3233' only permitted once per record.

I have multiple employees with this error.

All of them had multiple vesting of equity instruments for which we applied tax directives for. All of these employees has 2 or more tax directives loaded 

How do I fix this
