In Jira Plans, the summary provided of the Sprint ticket status is per below i.e. organised into Categories for TO DO, IN PROGRESS, DONE.

This is per the Status Categories defined in Jira Plans as indicated below:



However the Scrum Board which is the Issue Source for the Jira Plan defines it differently.
For e.g. category of "Not started" only accounts for tickets where Status = Backlog.



The mis-alignment of the Status Categories between the Jira Scrum Board and Jira Plans is causing confusion and making it more difficult to adopt Jira Plans by the teams here.
