Why don't I see all my display blocks / business relations / addresses / functions in the list of persons or on the profile page?
This can be done with the filter field "Limit contact information to Organizational Unit(s)" in the "List of persons" element. If a value is set there, only the contact information of the corresponding organizational unit will be shown. The site admin can globally set a default for this field, so even if the field is not set in the element, a filter will still be applied. You can override this default by checking "If above limit is empty: Contact information from all Organizational Units are shown".
If the above options do not work, it is possible that the cause of the error is in the GF-GUI (IDM). Possibly blocks with a "crossed out eye" are hidden there, or a filled in free text field overwrites the database connection.
If you are unsure, ask a site admin of your website.
