Altiris SW Delta Inventory - Add/Remove Programs

I found the following issue with SW Delta Inventory (Deafult options):

When adding a new program followed by SW Delta Inventory Task: the new program appears in Resource Manager/Licensed Programs

However when removing a program followed by SW Delta Inventory Task: the old program still appears in Resource Manager/Licensed Programs

In other words: the SW Delta Inventory Task updates new programs, it does NOT update removed programs.

The FULL Inventory Task however does update the list correctly (i.e. it does NOT show removed programs)

My server/client versions are the latest:

CMS 7.1 SP2 MP1 Rollup 2

Altiris Inventory Agent (Version=7.1.7860)
