Ignition - Perspective - Multi-State Button - resize on grow

Hi everybody,
For a Label, I could resize the text with the help of a STYLE - TextStyle (seen on other posts).
But, I couldn’t do the same for a multi-state button.
Yes, I could assign my TextStyle to classes of Selected and Unselected buttons but doesn’t work. Maybe is the problem on the fontSize ?¿
Any ideas will be apreciated.
Many thanks,

I tried to remove fontSize and fontWeight in order to have only classes property but not works.
I tried to remove also classses property on defaultSelected / defaultUnselected and put only on general classes: TextStyle_1 (my style in order to grow or small the multisate button) but neither works.
