Pivot table creates extra data in fields

I'm trying to create a pivot table, but there is a problem. Although my data only has 2 years (1996 and 1997), it creates a new year it calls "blank," and a lot of the data that is supposed to be under 1996 and 1997 appears under this "blank" year. How do I fix this?

See the attachments for the data and pivot table.
