Incorrect task ID when using tp!id

Hi,
I'm trying to insert link to task in escalation alert. I'm using Appian 7.0. I'm using tp!id for taskID.
When the user click on the task link from received escalation, popup with the following message show up:
There was a problem retrieving the task. This task has already been completed.
But the task is not completed, the user can open the task from MyTasks.
So I notice that the taskID in the link is wrong.
Why tp!id is giving me wrong taskID when I'm using it in escalation alert. ...
