I not using Tableau v8 so I can't verify this with your workbook, but I suspect that Tableau is treating your calculated 1/0 field as a continuous measure and therefore defaults to a range slider for the filter. If you move this field from the measures to the dimension area, it will be discrete and result in check box or radio quick filter (with or without the "all" option).
You could also change the 1/0 to strings "Active" and "All". ...
Thanks for the assistance Jim. That got me pointed in the right direction and I was able to get it exactly as I wanted it!
