Oh yeah, one explanation short heh.
When you visit ManHattan's LORE profile page, you'll get his publicly visible information, however if ManHattan has opted to not make his connection to his characters advertised through LORE, then you won't see any character names on his profile page.
LORE has many intricacies like this because we need to maintain options for personal privacy.
Some choose to use those options like answering "unspecified" for their gender, or not putting in any ICQ/MSN/etc numbers, or having the email address kept private, or blah blah blah, there's a lot of that type of stuff
