Service Confirmation payload

Dear Experts,

I am trying to confirm the service confirmation with reference to the service order via web service. But the actual duration for the line item not updating though i am sending the same through the payload.

My expectation is to confirm the service confirmation with actual duration and with order completion.

Please find the payload below and advice me what i have missed.. Thanks to looking into this.
