Comments Won't Work In Directory Plugin Even Though They Are Set Correctly In Settings > Dis

Hi,

I just installed the Directory plugin and the comments are set to "off" (see page here: http://www.yorbalindanow.com/listings/ ). I have everything set so that comments are enabled in Settings > Discussion, but for whatever reason it still says, "Comments Off." I have disable all other plugins and the problem is still there. Any ideas as to what is causing this issue?
