Overdistribution Tier Created When Un-issuing an Item

An overdistribution tier is created when we un-issue an item from a work ticket in which the item was never originally issued and the item has an on hand quantity in inventory of zero. This scenario occurs when we create a "rework" work ticket to add or remove items from an existing part. Is there a better way to handle this scenario in Sage? Regardless, the creation of the overdistribution tier doesn't make sense because we are adding items to inventory. The on hand quantity of zero must be the reason because when the on hand quantity is greater than zero, this error does not occur. 

An associated error occurs in the above scenario if the item being un-issued has unit cost history. If the item has unit cost history, Sage un-issues the item with a negative unit cost (see image below). If the item does not have unit cost history, the unit cost remains zero.
