In my active sprint, i have my board columns split in 3; [ Open, In Progress and Done respectively].
My sprint board used to show columns for each User Story and Tasks that I've created along with the sub-tasks that correlates within. (i.e. User Story A [Open, In Progress and Done; User Story B [Open, In Progress and Done], Task A [Open, In Progress and Done], etc).
Now, it shows the 3 columns with all User Stories and Tasks, they aren't split into individual tasks or user stories. (i.e. Open [User Story A, Task B], In Progress, [User Story B, User Story C,], Done [User Story D, Task A].
How can i return the board layout to it's previous state?
