Shane,
While running the pre-scan on my 8.1 Pro laptop, everything checked out except for a whole slew of parse point issues...all of which were files uploaded to One Drive. The files did not exist (except for thumbnails), so this led to a hunch: I chose to have all the One Drive files available offline, and once that download had completed I ran the Pre-scan again...problem solved! So, I just wanted you to know that it doesn't appear to be an actual issue, but folks might get concerned. I will opt for the Pro version soon!
