Understanding Financial Balance and Payments


I created in my new erpnext installation 7 invoices attached to projects, 1 opening balance and 1 payment. When I get into my GL report, I see something weired, I simply see that balance is empty, and that when a payment is recorded it looks like it is taken from the balance of the company … I simply don’t get it I followed how the demo (documentation) says, the client account is the debitors, and my company account is the bank (when creating a payment) and yet I have this

What I need is simply to understand why the balance is used for payments I receive, and how to correctly configure this, because now the balance is empty. Or maybe I read the report the wrong way ?

Any help would be appreciated, thank you
