Students that don’t use SAML login to register in Weblab don’t have a studentNumber, netid, fullname, initials.
In the exported CSV, fullname is used. Therefore no name appears for such students.

Fixed in commit 488c52c: CSV now uses the Person.name field instead, which is “$firstname $lastname” if they have a firstname, “$fullname” if they have a fullname, a name based on the e-mail address, or otherwise “$username”.
