For a specific user, sub tasks appear on the backlog view, in the "to do" section, but when I switch to Kanban board the user don't see these sub tasks only stories.
As admin I can see these sub tasks on the board and in the backlog so it is not a filter issue, also not permission issue since the user see these sub-tasks on the backlog view.
columns are mapped for this status.
What could be the problem?
