Editing Title of a page in Knowledge base doesnot affect expanded title list

My xwiki installation is the last one click package installation for 1st users. (xwiki-1.0-beta-6)
I still explore this wonderful tool

How to reproduce the bug

1/
Create a page in the knowledge base. give it a title.
Save it.

2/
Edit this page
Change the title
Save it.

3/
Expand the knowledge base list on the right hand side of the wiki page (below "blog" item, and above the "main" item
The title is not changed in this list. Hence there is no correspondence between them.

Is it like this on purpose ? I don't see the idea behind this, i think this is a bug

I rated it major as i think that updates betweens the pages and the list should be a must for the final release.
But i don't think it is very difficult to correct it
