Right now the values for first_name and last_name are automatically generated from a supplied "displayName" value by splitting it by space, which causes invalid values to be saved into the database, e.g., displayName "Charlie of Atlassian" is being converted to the first name "Charlie" and "of Atlassian" as a last name, or "Doe, Jane" is converted to "Doe," being a first name and "Jane" being a last name.
