Something weird is happening on that page. When i access the Country Code page the extra channel settings show up for a second but then they dissapear and only the country selectionbox is visable.
I noticed this behaviour with FW 184.108.40.206.235, 220.127.116.11.310 and 18.104.22.168.312. You can only select a country (NL in my case), thats all.
Tried it with 2 different browsers on 2 computers, Firefox and IE, and with two different Unleashed networks.
