Delete button is not availabe on Adjusted timehseer of V13.3. But the delete task button was present on V12.
Please find the screenshot below.
My recollection is that there was an earlier discussion on that. You can search this community discussions for that.
The problem was that if you delete tasks from adjustment timesheets the existing WIP entries do not get changed since there is no task.
So the work around was not to allow task deletion.
The proper solution which was to have the WIP entries adjusted even if teh task is deleted, was to cumbersome to develop.
