Balance Item disappered in Account window

Hi,
As a fan of HomeBank, I really appreciate you for your smart product.
My problem is that the balance list item has disappeared.
I added about 200 transactions and tried to arrange list items. While I was moving and resizing some list headers, I found that it was not there.
I tried to reshow the Balance item but failed.
Balance item is very important for me to check whether my input data is correct or not.
Please help me.

Thanks.
