Hi @theresalech ! This PR is ready for livio team review!

[ValeriiMalkov]

Seems like it would be cleaner to just shorten the content of the label

  /*
   * Label with name of UILanguages select
   */
  appUILanguagesLabel: SDL.Label.extend({

    elementId: 'appUILanguagesLabel',

    classNames: 'appUILanguagesLabel',

-   content: 'application UI Languages'
+   content: 'App UI Languages'
  }
),

  /*
   * Label with name of TTSVRLanguages select
   */
  appTTSVRLanguagesLabel: SDL.Label.extend({

    elementId: 'appTTSVRLanguagesLabel',

    classNames: 'appTTSVRLanguagesLabel',

-   content: 'application (TTS + VR) Languages'
+   content: 'App (TTS + VR) Languages'
  }
),
