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    763001000010021    TR570004600763001000010021
0046-00763    763001000300621    TR970004600763001000300621
0046-00763    763001000071087    TR820004600763001000071087
0046-00763    763003000054029    TR180004600763003000054029 Last IBAN Code.

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