Incorrect fragmentation report

I have noticed that lately, Piriform's Defraggler has been having issues reporting correct information with the state of the drive's fragmentation.

I have included a screenshot showing the issue.

P.S. I should not that I have already disabled VSS while defragmenting, but no change in the incorrect status.

Is there a fix for this yet?

all that tells me is Disk Defragmenter fails to detect 774 files that are fragmented.

if you click on one of the red squares on the DF map it'll show you the file in question.

maybe that will suggest why DD opts not to include them.
