Inventory Managment generating stock points for items without sales

2010.2

In our account, Inventory Managment is generating stock points for items without sales in the order analysis interval.

Items are receiving stock points even though they have not been sold for over 2 years.

Inventory Management should only generate stock points for items with activity in the look back Order Analysis interval.  I see above to mean - the last six months from today (not the last six months from the most recent sales order which is what NetSuite is calculating).
