I need to count the number of resolved tasks. A task is considered closed (crossed out on the board) when it changes to the green closing status. From the documentation: Issues resolved are those that have a resolution date, and Issues closed are those that take into account the date the issue was finally closed (that is both, issues with resolution date and issues without a resolution date). Can you help me figure out why some closed tasks (which have moved to the closing status and are crossed out) indicate the resolution date, while others do not? How do they differ and what determines whether the tasks is resolved or closed?
