Bio info for authors disappears

I have a wordpress blog that has multiple authors. I also created a page with authors template so that a summary of all the authors contributing to the blog can be seen.

Each of the authors have their own bio info, but I’ve been having a problem. The bio info disappears after they have logged in. Even if they did not edit the profile page.

I have to keep updating the profiles and they will disappear again. Very annoying. Any ideas?
