Can't choose ProFTPD in Global Config on new HC8 Cluster install.

Am setting up a brand new HC8 cluster with Server 2008 R2 Standard & CentOS 6.2 x64. I am unable to choose Proftpd from the global config as it keeps going back to wu-ftpd after every save. I have tried editing it from my computer and from the server and am unable to save it. Where in the HC database is this setting so that I can manually set it to Proftpd?
