Task locked up

[jfargo]

I have a task that was cancelled and the Last time says cancelled but when I try and modify it, it says "This task is running, please stop the task before setup it". I can't delete the task as well.

I restarted the service, I've clicked Stop Task, and nothing seems to unlock the task. Service.log is below.
