They will of course be in the old backup.
If you make a new backup the duplicates will be gone in that file, so if
you want to go back it's probably a good idea to keep the old backup
file.
Of course, as you continue to play music in your library the old backup
file will be inaccurate, so it's probably not worth much to keep it
after you have verified that things seems to look as you want.
If it looks like your rating/playback statistics looks reasonably
correct now, I would suggest that you just make sure to disable the
musicbrainz setting in the TrackStat settings page and enjoy the music
instead of investigating the duplicate issue further. Feels like it's
going to be a lot of work to fix it manually and I doubt it's worth the
trouble if it looks reasonably correct now.

I can confirm that you have found the problem, the behaviour in
TrackStat currently is that if an unrated track is played longer than
the lower limit but not long enough to increase the rating it's left
unchanged rater than set to the default rating value. I'll put it on the
todo list to fix this, but I want to make really sure I don't break
anything else so it will require a bit of investigation and due to this
make take some time.
