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 22.214.171.124.235, 126.96.36.199.310 and 188.8.131.52.312. 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.
