'This status is managed internally by JIRA Software' description shows for some issue statuses
When administering JIRA Software, you may find that some issue statuses have the following description:
This status is managed internally by JIRA Software
This may lead to confusion on whether these statuses are safe to edit or remove.
This description indicates that the issue status was created manually on an Agile board (Configure > Columns > Add status).
These issue statuses can be treated as any other issue status. They are not required by JIRA Software and can be modified or removed.
