Accounts that have a DR & CR that sum to $0.00 appear on PNL

GoodAccounting

I've attached a picture to show the error. If I earn income, but then have to refund that income, which results in the account totaling $0.00, this balance still shows up on the PNL. PNL should only show accounts that equal anything but $0.00.

The end result is it makes the PNL longer than it needs. Can you guys fix?

Thanks in advance.
