When any back dated stock transaction is cancelled then repost item valuation get stuck in Queued and stock ledger is not getting updated. I have tested this on latest [Release v13.0.0].
Later if we post any new transaction for the same item in current date then the item valuation gets updated only for the new transaction and stock balance value get corrected however, all the previous transactions which were recorded prior to current transaction still show wrong calculation in stock ledger.
