We do not have a misperception. But you are misusing the program and violating fundamental accounting principles. You cannot receive money for a payable. You pay money to suppliers for payables. You receive money from customers.
You can assign accounts to groups and collapse the groups. But first you must get your accounting straightened out. Then realize there is no purpose for the accounts you created.
You will note that the default “Control Account” for suppliers is Accounts Payable. You can also set up a different Control account for suppliers with a different name such as Creditors. If you create a different Control account then this can be selected when creating or editing a supplier (see this guide: Add custom control accounts | Manager)
You must first create the supplier before entering any invoices.
Looks like @yhoga just wants to have a control account for loans.
You can create a control account made of Suppliers and give it any name you like, such as Loans or Debts. Create a supplier (Financial Institution) and put this supplier under the new control account. When recording your cash receipt from the financial institution, choose his control account and select the financial institution.
A control account comprised of “Special Accounts” is another option.
