Time Machine - Apps not visible

Hi
I've been running Time Machine for a few months and assumed everything was being backed up but yesterday I noticed that when I "enter Time Machine" and click back a few days / weeks or even months that my Applications folder shows "no items".

I don't have the Applications folder masked off or set to be excluded in my TM prefs so was wonderign what gives?

Running Mountain Lion 10.8.4, 1TB Time Capsule (2012) and a 2011 MacBook Pro.

In the meantime I came across a similar thread and removed my TM prefs, reformatted my TC HDD and started again. All seems to be backing up fine this time.

I'm glad I also do a complete clone of my HDD with Carbon Copy Cloner. Phew!
