CurrentUser becomes user number in saved searches

When I create this search for my self it works fine:
( AdminCc.EmailAddress LIKE ‘jmccoy’ OR Cc.EmailAddress LIKE ‘jmccoy’
) AND ( Status = ‘new’ OR Status = ‘open’ )

( AdminCc.EmailAddress LIKE ‘CurrentUser’ OR Cc.EmailAddress LIKE
CurrentUser’ ) AND ( Status = ‘new’ OR Status = ‘open’ )

AND ( Status = ‘new’ OR Status = ‘open’ )
