Beatgrid and BPM shift issue in Traktor Pro 3.11.1

Julcsi

I am experiencing a persistent issue with Traktor Pro 3.11.1 (Build 17), where all my tracks lose their manually set beatgrids and BPM after I put my computer to sleep or restart it or just if I haven't use the music for couple of hours.

Here is what I have tried so far:

• I manually set the BPM and beatgrid on MP3 and M4A files. First I used M4A I had the same issue, then we used MP3 for the same musics
• I locked the beatgrid using both the grid lock and the track lock (Lock BPM & Beatgrid).
• All my tracks are located on the internal SSD (Mac), with full read & write permissions.
• Auto-analysis when loading into deck is turned off and ID3 tags write on/off tried
• I tried also not to use the lock icon after manual beatgrid set, only saving
• I don’t use any external DJ software
• Reinstall traktor software (using latest OSX and Traktor)
• Settings and collection .nml files relocated, made new
• I turned off the snap (as how I read here as an optional help)

Despite all this, every track slowly shifts its grid position – even though everything seems to be saved initially. After putting the laptop to sleep or after a restart, the beatgrid is off by a small amount.

This issue happens consistently across all MP3 tracks, not just a few.

Could this be a metadata saving bug in the current version, or something related to how Traktor handles MP3 tag writing?

I would appreciate any assistance or suggestions on how to solve this issue.

Thank you in advance for your help!
