Soft Commitment is not getting clear

I have Inventory at primary location and Inventory adjustment, and Sales stock relive from Primary location only .

Ship confirmation of sales order is being automatically schedule by calling R42500 > R47500 > p4205.

But after ship confirmation , Soft commitment is not gets clear for respective Item + BP . We can see proper entry in cardex but item balance gets incorrect as soft commitment not gets removed, Even i could not see wrong commitment in P42210 . hence i need to know the standard cause of such scenarios why soft commitment not gets clear although ship confirmation gets successful and cardex gets updated
