In Advanced Roadmaps, Grouping by Sprint shows the same sprint twice

[Eirik Aune]

I am looking at the timeline in my Advanced Roadmaps, and am grouping by Sprint.

Something that I am seeing is that the same Sprint is shown twice, and splits the issues in the sprint between the two sprints in a way that is not obvious to me.  Why is this happening and how can I stop it?

I have a single data source which is a board for the Plan that includes multiple Jira Projects.  Only one of the Jira Projects has the Sprint inside it.  You can see that the sprint is shown twice.  The SA Project shows in both of the sprint displays.  The same is true for SHMM but it is cut off of the picture.

I have been working on this a week, and obviously the answer came to me immediately after I posted for help.

The answer is that the Team field is not set for the second group, but it is for the top group.  It wasn't obvious to me because we overloaded the team name ("C&A SW Topside Controls Apps) to the board as well.

If this is happening to you, it's because of the Teams field
