Filter not working as expected. bringing all data sets

Hi,

I'm in Design Studio 1.2. My dashboard has multiple categories and each category is represented by a Button in the Dahboard. When I click on a category, it displays the corresponding result set in a graph and a table.

When there is no data for a particular category in a month, I would expect my graph and table to show no values, when I click on that category. But now it shows me all the records in graph and table. The filter for some reason is not working and that brings all the records into the graph and table.

When there is data it works fine. It shows the corresponding data for selected category.

Is anyone has faced this issue?

My dashboard is based on universe.

Regards
