When creating a new bug in the backlog, it immediately disappears with a notification saying it is hidden. This bug can be seen on both the Kanban (Agile) boards dedicated to QA and Implementation. The problem is this bug cannot be managed in the Backlog, where older bugs can. Is there a way to make this visible in the backlog?
The bug is created under all issues, all stories, with no filters applied.
