renamed? event types can't be found

On the demo site I can find the participant in the event ARC by searching for it by Event Name but not event type.

I renamed the event type after registering the participant in the event

http://drupal.demo.civicrm.org/civicrm/event/search?reset=1

enter ARC for event name and 'Class block 2 2008' for event_type. no results. if u remove the event_type u get one participant
