Missing Info In Traktor

When Im In Traktor and open up the iTunes section and go through my library there, several items are missing in the playlist section such as: cover art thumbnail, label info, and key information...Do these only show up in traktor playlist / collection area or do I have something disabled?

Also I normally do my editing in iTunes then move to traktor where would I edit the label & key info in itunes to show in traktor?

how can I edit label tag in itunes? is it possible

No, but you can do it with kid3 and most tag editors.
