HI,
I'm using the next gen version of jira
When I create a task under an epic, or a sub-task under a task, the status/progress bar indicates that the task is complete while it was just created and still in 'To do'. Then as the task progresses from 'To do' to 'In progress' to 'Closed' the status/progress bar goes in reverse. In the sense that when the ticket related to the task/sub-task is closed, it then indicates that 0% progress has been made on the task.
Its exactly opposite to what it should be.
I believe this is a bug and needs to be reported.
