Ielts result date

[Anpman]

Hello all
While filling my IELTS detail, it asks result date.I gave my exam on 8th September and result came out on 21st September.
But on report form date given is 19th September.
Which date should I put in result date column while filling my express entry form? 21st/19th September?
Thanx in advance
