Task and Sub-Tasks changed to Cancelled Status

Hi,

I have a User that is trying to raise a requisition and charge against a Project and a particular task in the Project, but it appears that the task they are trying to select has been changed to 'Cancelled' status along with all the sub-tasks for this task.

This has all been done in Projects Self-Service but in Forms the Task still looks active and live,

Am I right in thinking that once a task/sub-tasks have been changed to 'cancelled' status this is irreversible and cannot be changed either manually or by way of a fix?

Thanks

Ian
