New KPI Card bug with custom formatting?

Hi, 

I have a problem with new kpi card with custom formatting. 

What I want to achieve is a custom formatting to show percentage number with unichar icon. So I'm changing in Reference Labels ->Value -> Display Units to custom (1) and then set up a measure to format code (2):

Created measure look like this and it's formatted as a text:

Rejected Rate YTD is a measure already formatted as a percentage number in tabular model.

There seems to be error with the percentage value because the format function does not do what I expect it to do, dot is missing:

With normal number everything works perfectly for example:

Bug also exists with for example milions like FORMAT(measure, "#,##0,,.0M"), the dot is missing and it shows 1430M not 143.0M. It occurs everytime when I want to use additional unit and decimal formatting.
