In Jira settings / Issue attributes / statuses we see a large number of statuses with 'Workflows applied (not editable)' under the 'workflow' column as they do not give us the option to delete them.
This would appear to indicate that they are being used in some workflow however we have reviewed all workflows as well as all statuses defined in 'next-gen' projects and they do not exist. We recognise the status names as ones we created before so they are not system statuses.
My guess is these are orphans from previous next-gen projects that were deleted. Is it possible to remove these statuses?
