That old CWP interface was always crippled and shouldn''t really be there now - use the one at the bottom of the menu system.
If you were a touch more observant, you'd notice a (blank) dialogue box appears, when you press the CSF Status button at the top of the same page - obviously it doesn't work i.e. no output. One of the many small bugs?
I advise everyone to use the native CSF interface instead.
