Issue with not seeing 'unviewed' candidates

Summary

The requisition view shows that there are unviewed candidates but recruiter can't see them (none are bolded)

One of our recruiters says her requisitions show that there are unviewed candidates but when she opens the requisition she can't find any.  Has anyone else had this issue?  Is there a chance there is an issue with the view we have set up?  Do 'knocked out' candidates not show in the requisition/candidate view but still count as unviewed?
