Thank's Evertjan, unfortunately it is not it. I suspect something goes wrong out side function, i really do not get it because after i set to zero. I still can't remove the two last tracks but they are visually written out, but they can't be there because tracknr = maxtrack is down at zero. I will have to check what is going on elsewhere, because the maxtrack and tracknr goes down to zero but the two tracks still written out. I have to check track.length with console.log.
