How do you fail budgetary controls / funds check for Ledger?

Our setup (per shown below):

Ledger or Projects

With these journal exceptions. There are several Journal Sources that haven't been added to these exceptions as per below drop down image.

We are going into the GL's 'Inquire and Detail Balances' and reducing them (assuming these are the non-project control budgets). But when we are testing, even a massive amount like 20 billion, for PO's, invoices etc. it is still passing funds check? We are stuck.
