In Jira Cloud I have an enterprise managed project / space with tickets that have a custom workflow.
For this workflow I have a Kanban board that has one column for each workflow status.
If I import issues from a CSV file, the tickets are shown in the Kanban board correctly.
The Cumulative Flow diagram however, displays the tickets as if they all have the same status. If I change the status of an imported ticket, this is also not reflected by the diagram. Here it does not matter, if I change the status directly in the ticket, or by drag and drop in the Kanban board.
If I create a new ticket in the project via the big Create button in the top menu, things work all right.
Do you have any hint what goes wrong here?
