Unable to see some customize groups in Inventory report

I created a custom group and I want to filter by software for this group and retrieve report. But when I go to 'Inventory' report => 'Software Usage by Computer' , I could not see the group I have created. Also noticed a few other groups are missing. Anybody face this issue?
