Bank Account is not populating in AP Invoice but Supplier is secondary account owner

We have a business requirement to have the existing bank account shared between Supplier. As per the Supplier knowledge base, we did add the second supplier details as 'Secondary Account Owner' in the existing Supplier Bank account.

Steps followed,

 1) Navigate to Suppliers

2) Query the supplier that was found in above queries

3) Navigate to Sites

4) Then to Payments > Bank Accounts

5) If you find bank account that was found in above , edit the bank account and add the Account Owner (provide the supplier name which you would like to add this bank account) , and then save.

Now, when we try to create Invoice for the Secondary account owner, the Bank account number is neither getting defaulted nor available in LOV
