Solution Time longer than one set

[Riluin]

Hello,

I have problem with 'Solution Time' of my tickets. I have set a SLA with 'Escalation-solution time' of 40 hours for everyone of my tickets ( 40 hours counted in business hours, 8h per day).
However when I control the 'Solution Time' of a ticket in the 'Queue View' I can find time about '73 hours' ( as in the screenshot).
How is it possible?
I need tickets to escalate with the period I set.. how can I do this?

Thank you,
Riluin
