Have you updated Vue FilePond, FilePond, and all plugins?

• I have updated FilePond and its plugins

Describe the bug

I need to custom label-idle property so I can show to user how much file that they can apply..

expected result:
variable printed at label-idle property

what I get instead:
variable printed as string at label-idle property

Reproduction

this is my source:

<script>
import vueFilePond from 'vue-filepond';
import 'filepond/dist/filepond.min.css';

// Import image preview plugin styles
import FilePondPluginImagePreview from "filepond-plugin-image-preview";
import "filepond-plugin-image-preview/dist/filepond-plugin-image-preview.min.css";

// Import image preview and file type validation plugins
import FilePondPluginFileValidateType from "filepond-plugin-file-validate-type";

const FilePond = vueFilePond(
  FilePondPluginFileValidateType,
  FilePondPluginImagePreview
);

export default {
  components: {
    FilePond
  },

  data() {
    return {
      maxFiles: 3,
      files: [],
    }
  },

  methods: {
    handleFilesUpload(files) {
      const vm = this;
      this.files = files.map(files => files.file);
      vm.$emit('handleFiles', vm.files);
    },
  },
};
</script>
<template>
  <FilePond
    name="files"
    ref="files"
    class-name="class-pond"
    label-idle='Letakkan file disini, maksimal {{maxFiles}} file'
