The sprint participants picker (face bubbles/overflow checkboxes) does not remove participants when changing the sprint via the dropdown on the Active Sprints screen. So, if Sprint 1 has participants A - C and Sprint 2 has participants D - G upon a fresh load of the Sprint 1 screen, you will see the avatars for A - C, then if you change the sprint through the dropdown to Sprint 2, the avatar avatars for D - G will be added to the participants list, but the avatars for A- C will remain even though they are not in the currently selected sprint 2. The problem is resolved by refreshing the screen.
Is there a way to change this behavior?
