BuddyPress.org

Hi,
I am having trouble searching for a group from the directory. Normally when you hit letter A, the groups listing will return all groups starting with A. But instead it will list all groups regardless the letter I search from. I am using bp 1.2.4 with wordpress 2.9.2. The members search is working perfectly only the group.
Does anyone knows how to fix this please? or where is the function that does the search so I can look it through

Thanks for helping
