KPI Border spacing with Simple KPI Extension

[Timste]

Hello,

I want to create menu muttons with the "simple KPI" extension to navigate to other pages. When I use the css code below in my simple kpi extension, I get the buttons on picture 1. When I use the same code on multi kpi, I get the buttons on picute 2. Why is there a difference and how I can archieve the same results (border spacing) with the simple kpi extension?

Thank You

border-radius: 2px;
text-transform: uppercase;
