Hi,
The refund column is hidden within the Expenses section.
You can expand it by clicking the "Click Layout Assist:" button so it indicates "ON".
Then you click the double triangle above the Expense category bookmark, and it will show all of the hidden columns.
To keep any of these columns as unhidden you can delete the "h" at the top of the column. When you are ready to rehide the columns again, you click the double triangle again, and then turn OFF the click layout assist button.
I hope that helps.
Scott
