Your Summary reporting period seems to be for the month of February 2016. Adjust this by clicking Set Period at top of page. And you don’t seem to have an Accounts receivable account. It is impossible to tell from your screen shot whether you even have the Customers tab enabled. With no customer specified, a sales invoice will show as paid and be dumped into Suspense.

You also don’t seem to have specified an income account for the sales invoice line items to apply to. In fact, you show no income at all.
