BPM value disappears in Windows after CrossDJ analyses

Windows Vista and Cross DJ 2.3.0
This is something I have noticed in earlier versions as well. I typically have the BPMs of my files measured via the free "MixMeister BPM Analyzer" program. Several reasons including it's quick and easy to do, seems accurate, it populates the ID3 tag AND it does to the file whatever it needs to do so that the BPM value displays in the "Beats-per-minute" column (that I have chosen to display) in my Windows music folders.
I will then import the songs into Cross DJ. The BPM values from the ID3 tags are visible, but until I play and/or analyse the song in Cross DJ then I have a strong "in my face" clue against every file whether I have maybe played it or not when DJing with Cross DJ.
If you understand the above so far, then what I am seeking help with, is after I have analysed a song with Cross DJ, why does it always blank out the "Beats-per-minute" info via the folders view in Windows? The ID3 tag is updated, but something else is going on ...
