Dynamic Change type measure

I have an advance card and a Stacked column chart, with dynamic measures that looks like this:

Measure = 
  var meas =  min(_Measure[CoMeasure])
return
  switch(true();
    meas = "Rate%"; 100*[Rate]; 
    meas  = "Measure1"; [Events];
    meas = other measures.....
  )
And as measure:
Rate = [New Device] / [New Total Device]

The problem is that in my card, the value displayed "Rate%" it is not showed as a percentage, but, as a number.

And the barchart is showing different values:

Then in the dynamic measure, I change "Rate%" to this:

...    meas = "Rate%"; Format([Rate]; "0.00%") 
   

The Card visual it is showing with the right format, but the bar chart is showing nothing.

On the other hand, when I drag the measure "Rate" directly to the bar chart, it is showing the right values as percentages:

What I'm doing wrong? How Can I show the dynamic measure in the card, as % and get the correct values in the bar chart, also showing the right values?
