"Choose Files" still showing ontop of BROWSE button

[MileanCo]

I'm using Angular 1.6+ with Meteor 1.5+

Using the code provided in demo:

<form name="uploadForm" layout="column" >
      <lf-ng-md-file-input name="files" lf-files="ctrl.files" lf-required lf-maxcount="1" lf-mimetype="audio/*" multiple progress drag preview></lf-ng-md-file-input>
      <div ng-messages="uploadForm.files.$error" style="color:red;">
          <div ng-message="required">This is required.</div>
          <div ng-message="maxcount">Too much files.</div>
          <div ng-message="filesize">File size too large.</div>
          <div ng-message="totalsize">Total size too large.</div>
          <div ng-message="mimetype">Mimetype error.</div>
      </div>
      <md-button type="button" ng-disabled="uploadForm.$invalid" class="md-raised md-primary" ng-click="submit_upload()">Submit</md-button>
  </form>

I'm still seeing the default input field "Choose Files" on-top of the new BROWSE button/input.

This can be solved by doing something like https://stackoverflow.com/questions/26895125/how-to-hide-default-choose-file-button

but I figured this library should handle this??
