when I click on the little checkmark icon labelled "Task - Change Issue Type", I get 3 choices: Task/Story/Bug
why don't I see Sub-task? I have subtasks enabled. if I click Settings/Issues/Sub-tasks, I see:
"Sub-Tasks are currently turned ON"
so what else do I need for Sub-tasks to show up on the menu so I can convert my issue to a sub-task?
