Featured Groups

I’ve tried to follow the BuddyPress Codex for creating “featured” groups, but for some reason it is not working, any ideas? The featured group checkbox appears in the group settings, but on the group index page selecting order by featured does not actually change which groups are displayed. This is the code I placed into my Kleo-child theme functions.php.

//it’s important to check the BP_Group_Extension is available
if( class_exists( ‘BP_Group_Extension’ ) ) :
/**
* This is a quick and dirty class to illustrate “bpgmq”
* bpgmq stands for BuddyPress Group Meta Query…
* The goal is to store a groupmeta in order to let the community administrator
* feature a group.
* Featured groups will be filterable from the groups directory thanks to a new option
* and to a filter applied on bp_ajax_query_string()
*
* This class is an example, it would be much better to use the group extension API
