VAT being distributed to the VAT control account in AP Distribution But Accounting is showing full

hi

I am encountering a peculiar situation:

From front end you can see the VAT being distributed to the VAT control account (112102)  in AP Distribution.

However when you call up the accounting you see the VAT being casted and reverse. And the full invoice amount being distributed to the cost center.

What can be the cause of this, and only for the 4 invoices listed below.

Invoice Number	Invoice total Cost Distributed VAT distributed to Cost
E469523880	1941.77 1760.87 180.9
E469524731	1511.62 1388.2 123.42
E469525092	1020.2 954.25 65.95
E469838574	1713.91 1566.19 147.72
