Filled-in metadata are not displayed in view mode

On DAM, we currently display some metadata in view mode (title, desc, original author and creation date) and some additional metadata in edit mode (+ all dublincore basically). I first thought that we only displayed the filled in metadata in view mode, which is the behavior on DM side. But actually, filling in some field doesn't make them displayed in view mode. As a consequence, users with read rights cannot see the metadata values of documents.
