You mentioned they are out-of-unit members. Does that mean you added them as out-of-unit members to your ward in LCR? I haven't experimented with what that grants in terms of ward directory access and we don't have any out-of-unit members in our ward right now. If that doesn't grant access, then russellhltn is right, they might need callings.
I don't know if the new ward directory & map website has a unit selector the way some other tools do. If so, they might just need to pick which unit's directory they want to see.
