Members not showing for Group Leader

Hi There,
For some reason the members that should be listed under the Group Leaders dashboard are no longer showing. We have tested to see when adding a new member if it will show and the member is added successfully, but does not show as a part of the organization.

The site is closed and password protected, so let me know if you need admin access to check as I cannot post a link to the page in question.

Thanks,
Gabe
