When creating a new channel now, it gets sort order 0. That leads to both the Notifications Channel and the new Channel being sort order 0 and when you try to order the new channel down one, it moves the one beneath it up to 0 and it gets stuck.
Recommendation: New Channels get placed at the bottom.
Alternate Suggestion: New Channel gets sort 1, and all other channels have to get moved down by 1.
