Sometimes you will see profiles that have a dash under each column.
This indicates that a person is currently in enrollment and has not completed the process to be a fully enrolled user of the Rock.
When you click on the record, there will be no details for the person.
This is not to be mistaken with a user that is enrolled but their badge has not been configured to display the badge number. In this case, the information will be displayed for each column (Last Event, Site, Device Name, Timestamp).
