I created a new Next-Gen project and selected the Kanban board template, however when I went through to the board that had been created it was the Scrum board (To Do, In Progress, Done). It doesn't allow me to enable "days in column" metrics and I much of the other board management doesn't seem to be available. How do I change my board from Scrum to Kanban with a Next-Gen project, and why do we not have the admin functionality we usually have with boards (I'm an administrator and board administrator).
