I’m new to this but I think that you have to add a sidebar into the member-page. I haven’t got the solution you’re searching for but this is a lead to follow:

You have to modify the theme you’re using so that a sidebar shows. You can do this in

/bp-themes/yourtheme/header.php

Add:

<?php get_sidebar( );

At the end of the file.

This will probably not work so well with uncustomized themes. There’s no room for the sidebar to show up. You’ll have to modify the look so that the sidebar shows correctly.
