Instead of OPEN status in default jira workflows, it has been modified to "Spec Open" Status.
I assume that someone created new workflow ( made a copy) and edited the status 'open' to "spec Open" and that changes reflected to all other Workflows with status 'Open'.
Now we have active workflow with status 'open' and inactive workflows with 'Spec open'( including JIRA default workflows). The 'Spec OPen' status can not be renamed to Open status, as we already have it. How to return JIRA default workflow to Default state? How to fix this mess with statuses
