stacked column display does not change with slicer

Hello, 

I have a slicer that I would like to control two charts: a stacked bar chart, and a clustered bar chart. I only want to display the latest 12 months data. The clustered bar chart behaves as expected, displaying only that data. 

The stacked bar chart though, displays only the data for the last 12 months, but keeps all values of months, with nothing displayed for months that do not match the slicer condition. 

I would like the stacked bar chart to match the display for the clustered bar chart, and not even display the older months, as they contain no information. I include a screenshot below. Can someone please help me figure this out?

Thanks!
