[IT Analytics] Filters not working correctly

Hello everyone!

While working with IT Analytics cube, I've build one view with the following fields:

Computer: name > Computer: Model > Software component: Company > Software Component: Name

See below

Then use a filter in the above coordinate, using the field Software Product: Name

I uncheck the ones I'm don't want (due to lots of information): Microsoft Security Updates and Microsoft Updates and Hotfixes

However, once I unmarked the ones above, I supposed to see the all software except those ones

But strangely, I only see these products as a result:

And this result happens when I uncheck any other

Is this a bug from IT analytics on Altiris Console itself, or should I have a deep look at IT Analytics database and SQL Server configuration?

Thanks everyone
