Why Address Fields in the Bank setups of 11i Instance has been changed? Bank Accounts are not showin

Hi All,

I done setups of all Banks,Branches and Bank Accounts in 11i instance some days back. But now am wonder the Address fields have been disappearing instead of the fields ,only one box is appearing and address become mandatory.

Few days back I done setups of all the Banks,Branches and Bank Accounts and still it exist  but when am trying to pay an Invoice , Selecting the Bank Accounts one Error message is coming  as ; FRM-41890: List of Values contains no Entries.

I want to know why this change has been occured?

What should I have to do to bank accounts should appear in LOV of
