Numeric Range Slicer

Hi All,

I'm using the new Numeric Range Slicer (released to Power BI Desktop, March 2017) and it is not showing in the Service.  Are others having this issue?

According to this (https://powerbi.microsoft.com/en-us/blog/power-bi-desktop-march-feature-summary/) it should show as a list, but mine is showing blank...

Thanks,

Michael
