Sprint health gadget pulls other team assignees

[Deleted user]

In my sprint health gadget, it also pulls up assignees from the other teams.

I have checked the backlog & Sprint - I don't see anything assigned to others despite of team members.  

I have also checked the board settings and it doesn't have assignees other than the team.

I'm having the same problem. jql does not show this assignee as the assignee to any issue in the board's project, let alone the sprint.  jql on the sprint does not show this assignee either.  This is very strange.
