Last system scan date no longer shown on NIS2012?

Recently, I installed NIS 2012 and now I’ve just realized that NIS 2012 doesn’t display the date when the last scan was performed on my computer anymore (on the scan now tab). I don’t know if this topic was already discussed here, but is this some kind of bug? Because it was very useful for me to have an idea about when to do a full scan on my computer. I run NIS 19.1.0.28 (portuguese) on windows 7 64 Thanks.
