is repacking entry calculating wrong Weighted average cost if item have negative on hand quantity on

Dear Sir,

We are using JDE 9.2, and recently activated negative quantity on-hand allowed in Inventory transactions, Reclassification, Sales and other related transaction.

Where we found Item having Negative On Hand Quantity and while doing Reclassification entry system wrongly calculated the Weighted average cost which is impacting on Inventory value, sales margin and financials entries.

This abnormal JDE system behavior happening with only few items, can you please advise what would be possible reason and how to resolve this permanently ?
