But then why does changing it back, removing the child delegation then work? I'd like to see your dig query and response before and afterwards, but first you might want to help yourself by running named in the foreground with debugging enabled to see what's happening when you start your server, query it, reload the zone and query it again. Run 'named -g -d 3' for starters and see what that gives you.
