Smartlist - Missing Track not working V3.3.3 64bit Windows

Hi Guys,
Just come across something tonight - I deleted some tracks from my Hard drive, opened up Cross, in the collection list when I clicked the tracks they then showed the RED X - here is the strange thing, before I clicked them I used the smartlist find missing tracks by Track status RED X and they do not show, even when I know the tracks don't exist Cross smartlist does not pick them up?
Surely this should show any tracks where the track status is a RED X, is this a bug?
Cheers John
