Part isn't decreased from inventory after being issued

SUGGESTED

We manufactured a tank and received it into inventory.
It asked if I wanted to post it to a job cost and I did so.

But on the parts inquiry it shows that I have 1 in inventory, the only transaction reported for it is the receipt. Yet if I look at the transactions for the job I posted it to, I see the line item for it and the amount. I don't want to have to adjust 1 out of inventory, it should show as 0.
