work order not committing item in inventory

I don't know if I have a corrupt data base or some other issue but I have items that are on work orders that don't show as committed when you look at quantities in inventory.

Example:

Item x has on on hand quantity of 2

I create a work order and put 1 of item x on it and save the work order.

I look it item properties and under the inventory tab instead of showing me quantity on hand of 2, quantity committed of 1 and quantity available of one, it still shows as 2 on hand and 2 available.

any ideas?

thanks,

Jim
