Control Chart not counting an issue for August that began Dev in August

[Grace Hamer]

Hi Atlassian Community,

Can someone please explain why this issue was not included in the August Control Chart since it began development in August? It's instead being included in the September chart, therefore, throwing our cycle time off

Moved from Backlog -> Development 26/08/2025

Development -> Done 01/09/2025

The ticket did not move back to Development during the life cycle. The last update that was made to it, after Done was to change its Work Subcategory

Thanks

Hi @Grace Hamer

The Control Chart groups issues by their completion date, not when development started. Since this issue was moved to Done on 01/09/2025, it’s included in the September chart, even though work began in August.
