I think you'll find you are unable to add non-members - period. That ability has been removed from MLS/never added to LCR.
Non-member spouses can appear in the on-line directory based on the marriage information on the member's record. But as far as I know, the switch to allow/disallow that is controlled by CHQ. If it's not doing what the family would like it to do, you can call CHQ and have it changed for that family.
