The short answer is had you used a supported approach for updating your 
channel (and related) information and restarted the master backend, all 
would have worked.  This is exactly why we don't support direct DB 
editing of the data.

Our intention for the future is to make the supported approach even 
easier and more reliable (and, perhaps, even semi-automatic, eventually) 
so there's absolutely no reason for users to feel they need to do it 
manually.
