Hey Mike,
By enabling "Visible Groups" or "Separate Groups" in your Course Settings, this simply adds "group filter" into every activity, into all gradebooks, and into all reports -- it's the only way to get these filters to appear outside of activities. This won't prevent users/groups from using those activities (provided you leave the "Default grouping" as "None"), it will just allow filters to appear in the activities for the teachers to see. Then, based on the permissions your teachers have, they will only see users in groups they are in (unless they are allowed to see all groups).
Once you change your course setting's Group Mode to either Visible groups (this allows teachers to see that other groups exist in the drowndown menu filters but they wont be able to see the users within it unless they have the permission) or Separate groups (this prevents teachers from seeing groups in the dropdown menu filters that they are not in), then log back in as Vicky and see if you are getting the behavior you desire in the Activity Completion report.
