Kanban LeanLabs relies on specially formatted labels in your project for it's work. Kanban LeanLabs labels use the following pattern.
KB[stage][0][Backlog]
Where:
KB[stage] - reserved prefix for columns
[0] - position columns
[Backlog] - column title
LeanLabs board configuration by default creates labels

KB[stage][1][Analysis]
