Incorrect BPM even when set to not overwrite

I have noticed a few tracks have the BPM changed incorrectly. I bring the track in from MIK and set analyse to not overwrite anything, but it overwrites the bpm of some songs with the incorrect BPM (eg from 128 to 137.5)

The BPM you see in the track browser is just the BPM field that is found on the ID3 tags. When Lexicon analyses, it creates a beatgrid and analyses your track. The BPM that is a result from there can differ from what Lexicon analyses. What Lexicon analyses is leading and will overwrite the BPM from the track browser, so it is the same as your beatgrid.

You’ll also notice when changing the beatgrid BPM, the track browser BPM for that track will update too.
