Leads/Contacts invitees not showing up when an event is created from within a lead or contact.


When you try to create an event from a lead or contact...other users show up fine and can be selected, but any leads or contacts you invite do not.  The check boxes show up..but the text is not there..its like the text is in white against a white background...please fix.
