Landed Cost accural account amount remains in credit side

Dear,

I received the material with landed cost and I use the separate supplier for the landed cost like I create the PO against the "supplier number 1" amount is 1000 $ and apply the landed cost charges 50 $.

after the final receiving system create the GL Entry :   Debit Inventory Account with amount is 1050 $ and Credit is Accrual Account amount is 1050$ .

Now the problem is that when I make the invoice against the supplier # 1 and match with item receipt then system create the GL entry Debit : Accrual Account DR with 1000 $ and Credit Liabilty Account 10000. which is ok

Now I make the landed cost charges invoice against the supplier # 2 and match with the shipment so system make the GL entry . Debit Landed Cost Charges Account 50 $ and Credit Liability account 50$.
