For a Credit account, Payments should reduce Balance and Charges should increase Balance. Why is the reverse happening?
Your Opening Balance seems to be in the wrong column. You're showing it as a payment, which creates a positive balance in the credit account.
Credit/Liability type accounts normally have negative balances (indicating that you OWE) money. Change that OB transaction to the Charge column and I believe that things will resolve themselves.
Another suggestion is to not show the Amount column and only use the Charge and Payment columns.
