Journal entry doesnt affect bank account

You have to use the Receipt and Payment transactions to affect a bank or cash account.

You cannot use journal entries

This is clearly explained in the guides
Record a payment | Manager
Record a receipt | Manager

This statement suggests you did not set up your bank account correctly. A properly set up bank account will not appear as an option for journal entries, so you would not be able to select it. See this Guide: Set up a bank account | Manager.

Also, expense claims never involve a bank account of the business. Expense claims are for expenditures made by other people with their own funds on behalf of the business. See this Guide: Use expense claims | Manager.
