Bug in 4.1.1: STEMS "link" disappears if track's metadata was modified outside of Traktor Pro.

DJ NUO

Reproduction:

1. Add "track1.mp3" to Traktor Pro 4. Analyze.
2. Click "generate STEMS" in Traktor Pro 4.
3. See "link" icon on "track1.mp3" in Traktor Pro 4. STEMS version of the track loads successfully into the deck.
4. Close Traktor Pro 4.
5. Open iTunes (Music app on MacOS) or any other app to edit track metadata.
   1. edit Genre of the track (e.g. "Techno" → "Techno / Chill")
6. Open Traktor Pro 4
7. See "track1.mp3" in the collection
   1. "link" icon is gone & no longer visible.

Additional comments:

• There seems to be inconsistency on what kind of tracks it breaks, and on what - doesn't.
  • I'm attaching the file, on which it breaks for me.
