Yea, but I guess you missed the whole point. That's just the standard procedure for adding channels, which I can do and have done. It doesn't work for 31-38, the channels that allow transmit to repeaters, because they can't be selected - the selector jumps from 14 to 39. Radioddity support said I shouldn't have been able to enter a channel for 39 either but I can, so that's one of the nine. And that proves there's no good reason to block the others.
