Language not work

[adgalileo]

Hi, I'm trying to set the language to Spanish and it always stays in English. I am using Angular 12 and the "@ajsf/material" package: "^0.6.0-beta.1". I write [language]="'es'" in the html of the component and nothing happens. I have also tried creating a variable, declaring the value and it doesn't work either. also, in the playground "kitchen Sink" example nothing appears in the browser console, it seems that the "onChange" function does not work. any solution? thanks
