Cancelled PO still showing in Unposted Source Documents

We person checked the affected orders and each are cancelled successful the Purchase Orders view. 
When I cheque the presumption successful General Ledger enactment halfway - Unposted Source documents - I spot the Relevance Status arsenic Irrelevant. 

When you people a papers arsenic Irrelevant it does not mean that we cancel it, but that it is marked arsenic Irrelevant for Accounting. If you filter with 'Unposted Source Documents', the papers volition nary much appear. The Relevance Status appears arsenic Irrelevant and the Processing Status stays arsenic In Process. This cannot beryllium changed successful the strategy backend.
