Gap Placed Between Bands

[roben1]

I am using Jaspersoft Studio v6.0.1.

I have a band with 2 columns.  The 1st has static data, the second has a single table that populates based on a query.

When I return multiple rows in the table in the 2nd column it adds an additional space between that band and the next band.  When I return only one column the space does not appear between that band and the next band.

Can anyone tell me why these gaps appear and how to resolve?  I have attached a screenshot of the layout, preview with multiple rows & gap, preview with single row & no gap, and the jrxml before modifying the query to return only 1 row.
