Thanks.
I'll have to look into this more, but it looks like there might be a bug that is causing the site to not fully recognize members when they are added through an organization.
For now the work around would be to add members to the site individually (not through the organization).
The simplest way to do this is through the Control Panel
Make sure that your site is selected by the site drop down.
Then go to: Site Membership > Users > Assign Users
From here you should see a list of users with check boxes so that you can add multiple users at once.
Let me know if that helps.
