problems deleting obsolete software and adjusting licesences

Good Day,

I didn't see this listed in the post so here it is. I actually have two questions.

1. When I try to delete obsolete software from the scanned software in the inventory, it asks if I am sure if I want to delete the software, then it just refreshes the screen and the software is still there in the inventory list. Do I need to do anything else to remove the software license from the inventory?

2. How do I demote the number of licenses issued to a particular piece of software? All I can find is an add licenses, I need to remove licenses from software in the inventory.

Thank you in advance for you help with these questions.
