'Norton Insight - Application Ratings' > 'Untrusted files' lists 'trusted' files

Why are there some 'trusted' files in the list of 'Untrusted files' in 'Norton Insight - Application Ratings' .

I did not cancel the 'Collecting Files' operation running.
I did not click 'Trust All Files'.

I found 'solved' message in 'Norton 360 v6 Public Beta' community which says " Fixed with build 113 NIS 2012"

but I 'm using newer NIS2012 19.5.0.145 on WinXPSP3. 

If same issue was fixed in 113, then 145 has a regression issue.
