Stack rank increasing by itself in TFS (Kanban)

Question

I'm having a weird issue in my TFS user stories (Kanban). The stack rank are apparently increasing automatically, as if the user is doing it (see screenshot).

Why does it happen and how can I disable this behavior?

Answer 1

It's a result of moving user stories on the Backlog tab. Each time you drag and drop a user story up or down the backlog, its Stack Rank gets updated automatically to reflect its change in priority related to other user stories.
