Not sure what you mean by 1. But every channel is numbered, always. Maybe whether or not to display it depends on the skin?
As for 2: no, not a problem, and is used here daily. Are you sure it is imported properly? Config ok (UK source was recently renamed)? Is the time on the box ok?
On 1.... Ok on 4.0 openpli its possible not show number in channels
On 2 .. yep i config like on 4.0...import success with 63.356 entries but these are not show on channels ?!
