Custom Attributes displaying inconsistent in Reports

Custom Attributes displaying inconsistent in Reports

We are experiencing that a custom attribute field is not populated consistently for two of the reports.  When running the Users Reports - All Users report from the main menu, only one user displays.  When running the report Exchange Reports - Mailbox Enabled Users, there are four users with this field populated which is consistent with the LDAP exports.
 
In the Admin>LDAP Attribute setting, the custom attribute has been Associated to both the User & Exchange Reports
