Control accounts incorrect on balance sheet

I have two bank accounts which are summarised under Cash at bank on the balance sheet. I tried adding control accounts to show them separately on the balance sheet but it does not work properly. The two accounts remain totalled under Cash at bank while the second account shows separately with the starting balance instead of the current balance. How can I assign them correctly? Screen shots attached. I am using version 20.8.96 on a Mac desktop.

You didn’t assign any bank account to the two Control Accounts. They both are assigned to Cash at Bank (2).

@Davide is correct. To fix this, you need to go into the Bank Accounts tab, click Edit for each bank account, and select the appropriate control account.

Thank you both, that has it sorted.
