Hello
We're having an issue with our inventory valuation, for some reason it's posted negative values to the G/L for 4 items. I've attached a picture below filtered to one item to show the issue 
As you can see the quantities and pricing in and out for the year to August are correct and matching, but we are left with a negative cost posted to G/L. Is there a way this cost posting to G/L can be manually adjusted?
Thanks,
Tim
