traktor pro - id3 tags not updating in track collection.

Hi all,

Seems like a strange problem, hopefully someone here can help:

I am using mp3tag to update the id3 tags of my mp3s. In Traktor, if I browse to the track through the software's Explorer it shows me the updated tag. If, however, I look at the same track in Track Collection it shows me the old tag. How to get Traktor to update the tags in Track Collection?
