Stack bar chart overlapping x-axis


does anyone have an idea, why the base of the stack bar chart is overlapping the x-axis and how it’s possible to fix this?

There’s the option to stet ‘base’ for regular bar charts, so I can move the bars a little bit up.
However, this doesn’t work for stack bar charts.

Thanks in advance
