FQDNs do seem to not work w/Nagios 2.4/nsca/bb2ns

I am using bb2ns, nsca and Nagios 2.4 and when I have the hostnames in NetBIOS name format both on the agent and the Server configurations, it accepts the client data just fine and has no problem displaying and logging them. But when I set the names to fully qualified damain name format, when the data comes into nagios log the name is comma delimited and Nagios does not map the name so it does not display or record its history. Has anyone else run into this and/or have any suggestions on a work-around?
