I have a software project for tasks called ET. I use a filter to bring in tickets from other projects to organise into sprints. When I view the backlog for sprints or the active sprint, there are no tickets for ET listed, despite there being tickets in the active sprint. I have tried changing the filter, and that view does list the tickets in the ET project. But when I go back to the backlog or active sprint view then there are no tickets in the ET project.
Could there something stopping tickets of the 'task' type being shown in the backlog or sprint view?
