traktor pro - how to update tags in track collection?

I'm not getting much help on the Native Instruments Forum so I'm hoping someone here can help.

I've used mp3tag to update my id3 tags, and the updated tags show up if I look at the track through explorer in Traktor Pro. However, if I look at the same track through Track Collection in Traktor, it still shows the old version of the tag. Can anyone please tell me how to update the tag info in Traktor's Track Collection?

Perhaps a look into the manual tells you whether this program uses its own database (i think it does) and how you can update the database (Import folders into the Track collection).
Please tell me, if this worked.
