I have started a sprint containing Stories with subtasks. The subtasks have original time and remaining set with total of 170hours across the entire sprint.
The issue is that the Burndown chart only recognises the remaining time on the subtasks that have time burnt down.
The Project has been working as expected up to now. Also worth noting, these tickets were rolled over from a previous sprint which seems to have caused this issue and that the original estimates are calculated by a custom automation.
I've realised if I log any burn on the subtask the total hours to the sprint increase to the full value of that one ticket.
