I have just begun the "Jira Essentials with Agile Mindset" course. I've create a team-managed project and I want to add a new column to my workflow. You can see in the screen shot below that I have created a column called "Review". 
My new column has a yellow exclamation point indicating a problem. I am told to "Drag a status here to assign it to this column". I don't see where to drag the status from? This is a different scenario than the one I am trying to mimic in the course. How do I get past this problem.
Is the problem that I used the "Scrum" template instead of the "Kanban" template?
Long story short, how do I add new columns into my team-managed Scrum project?
