Excluded Groups doesn't work?

Excluded Groups doesn't work?

I'm testing ADmanager Plus for our environment and was testing on excluding specific groups of employees that are technicians shouldn't be able to see or edit.  But after adding groups and even a specific OU for testing purposes and going ahead and signing in as the technician that has the exclusions I still see the OU and a profile that's under the group that was excluded while trying a task.  Everything else seems to be functioning just fine but excluding Groups doesn't seem to be working for me. What can be the issue?
