Most likely the channel is just a forwarder or something of the like. The forwarder for Configurable USB Loader (found here) displays as "???" in the Data Management screen. The problem can be fixed by using IceFire's application "WADDER" and editing the title. But it's usually no stress.
As for the Twilight Hack saves, delete the save entirely from Data Management then start the game, or just overwrite the file
