Cant get locale to change

[LamprosPitsillos]

// formkit.config.mjs
import { defineFormKitConfig } from '@formkit/vue'
import { rootClasses } from './formkit.theme.mjs'
import { el } from '@formkit/i18n'

export default defineFormKitConfig({
    config: {
        rootClasses,
        locales: { el },
        locale: 'el',
    }
})

// main.js
import { plugin, defaultConfig } from '@formkit/vue'
import config from '../formkit.config.mjs'
...
app.use(plugin, defaultConfig(config()));

I even tried putting the button from the docs to change locale manually and still nothing

                <button class="border-2 px-2 py-1 mb-4" @click="changeLocale('el')">
                    Set to Greek
                </button>
