That's odd, but it probably doesn't affect the normal operation of the puck as you've mentioned everything else seems fine. It might just be a dodgy LED. If it becomes a nuisance you could phone Sky and ask for a replacement which they may honour, although for a small issue like this perhaps not.
Keep us posted if there's any further regression though.
