Ah my bad, I've access wrong site just now.
I believe the menu https://test.themannareserve.org/index.php/downloads/categories is not reflected to the menu setting.
Is it possible for you to provide us with the FTP access to your site to check on this issue?
You can add the information needed by edit your first post in the Details section or you can just include your site's access once at http://stackideas.com/dashboard/site rather than needing to keep adding them in your replies
