If you have a HABA game with 5 alternate titles, all of the titles correspond to the existing version.
If we're talking about a new title because it's for a different edition, it's preferred that you add the name for the Dutch edition by adding a version entry. Alternate names should correspond to one of the version entries on the version list.
The name (and publisher) will float up to the game's header. You do not have to add them separately.
This is more efficient; it saves corrections that duplicate effort (for both of us) and saves the possibility of alternate names in the header that don't correspond to a version.
