I cannot get any of the channels onPress OK on your remote. Select the group you want to edit eg sport news etc. Press Exit.
Menu - Channel - TV Channel Editor
Select the channel you want to edit.
Red button - Rename
F2 button - Move.
I wouldn't bother messing with it too much at this stage as they are working on the EPG.
Loading a new file will wipe all the changes you make now anyway.
(If you notice in channel editor at the top, the group titles are wrong in that section, but the channels are grouped correctly)
I posted an update here yesterday
