I have created a new ScrumBan project in JIRA including a Backlog of 24 stories to start with. However, to create the first sprint for the ScrumBan project, the "Create Sprint" button is not appearing with the Backlog like it appears with the Backlog in Scrum projects I am using in JIRA. . For a Scrum project in JIRA I do see the "Create Sprint" button with the Backlog. I don't see the "Create Sprint" button with the Backlog in the new ScrumBan project.
