Hosts file malformed, hostname on different line than IP

[jrble819]

On OSX hostmanager is working almost as expected. It updates the hosts file with the requested aliases, however it is malformed. The hostname is placed on a new line after the IP address (see below). I've tried many different things and can't figure out why it's doing this.
