The problem is that the Project Backlog is showing one future sprint section per sprint *per Component*, not one future sprint section per sprint.
Scenario: We have one project with 6 Components. We have a board that is simply the overall project board (filter is simply "Project = AC"). We have two future Sprints (named "AT Sprint 5" & 6).
The backlog view breaks up the future sprint section by component, as such:
AT Sprint 5 for Component 1
AT Sprint 6 for Component 1
AT Sprint 5 for Component 2
AT Sprint 6 for Component 2
&c &c
(the Component value is not shown on the cards but when I made it visible that's how I determined it was grouping by component

Even the "detailed issue view" appears to sort issues by Component by default.
IS there a hidden default that groups issues by component around future sprints? Is there a way to change / eliminate that default if so?
