Can you still share a library backup file or will that not be possible? I just want to test with all of your same settings and see if I can trigger the problem in some of the songs in your library. I wasn't performing a two-way sync during my testing, as that generally is much messier when it comes to synchronization, so I will switch to using that to see if it is somehow related. If you can't share a library backup file, then at the very least, it would help to have all of the .xml files under the Windows 10 version's default storage location (the LocalState folder). Another option would be for you to export some songs using Share->Export as .msf, and I can test with those, and see if I can trigger the same behavior you are seeing. I just know that with my basic tests, I can't reproduce it at all, so I'm either missing something or doing something differently than you.

Thanks,
Mike
