NIS Full Scan While in Safe Mode. No Record of Scan.

A full system scan was performed while in safe mode using NIS version 18 (fully updated).  Done yesterday.  When I now open NIS and check in "Scan Now" link, the button for Full Scan indicates last full scan was a month ago.  Is this normal, that NIS may only remember a full scan if it were done in regular Windows mode?

 

In any case, NIS found no problems.  Scan was about 35 minutes for about 110000 items scanned.
