As mentioned, it appears you've somehow created your Roku account in the wrong region, which is why you aren't seeing the correct channel selection for your location. You'll need to be using an internet connection located in the region in which you intend to use your device, in order to create your account in the correct region.
Please feel free to send me a PM with your Roku account email address and the serial number of your Roku device from Settings>System>About. I can assist you further in getting this sorted out.
