Question about snort Categories and Rules

[whiggy]

Please look the follow screenshot:

As you can see on this screenshot, there is the category "snort_virus_rules".
In relation to this picture, should be 34 rules in the category, but I cannot see any one.

This issue occurs also in another categories. For example: In the summary stands 10 rules, but effective are only 6 etc..

I see this as well in some categories. I was wondering the same thing.
