Reply to MiK notation overwritten by Traktor, not wanted

Although I know this isn't the right community , this is the closest topic to my issue with Traktor (why is there no Traktor or NI software community ??)

Here is my case: I just updated to 2.6.4 from 2.5 and I thought the key detection addition was a good thing until I found out it is worse then Mixed In Key. And that's when my troubles started. Ever since 2.6.4 after analyzing tracks Traktor changes the Key tag in the MP3 file, therefor I loose my Mixed In Key notation (not in my track collection but in the original MP3). With it comes the problem, when I take my drive with my playlist to someone else I can only see the notation changed by Traktor.

Is there a way to disable key detection or the function to write ID3 tags on MP3s? I want my Mixed In Key notations back and if there isn't a way I'm forced to downgrade back to 2.5 again unfortunately
