Editing Channels

I have the hang of editing channel lists using DreamboxEdit, Dreamset and E-Channelizer, but have a question, on 28.2 most ITV channels don't show their regional name unlike BBC1, so I manually renamed them then sent to my box, all sent no problem, check on the box and regional names showing, then go back five minutes later, and they have gone back to ITV, how are the channels renaming themselves? It's only a minor problem, but annoying me.

Good point, thanks Techno, I will do that, saves me pull my hair out.
