Replacing IBAN From FI12

Hi All,

When I creating housebank, System is Changing to IBAN Codes.
All House banks IBAN Codes, changing the last IBAN Code.

For Example;

Bank Key        Bank Account                     IBAN CODES

0046-00763    763001000030019    TR570004600763001000030019
0046-00763    763001000200601    TR970004600763001000200601
0046-00763    763001000271487    TR820004600763001000271487
0046-00763    763003000254529    TR180004600763003000254529 Last IBAN Code.

When enter the Save, The system is changing All IBAN code to Last IBAN Code. per IBAN.
