title: Botpress UMM send letter by letter with Facebook Messenger
body: <p>I'm using <strong>Botpress</strong> to make a simple bot to <strong>Facebook Messenger</strong>, when I use simple String in <code>AddQuestion</code> method, all works, but when I change to use UMM is sent to user letter by letter.</p>
  
  <p>My <code>content.yml</code></p>
  
  <pre><code>identification_cpf: 'Preciso que você me infome seu CPF (somente números)'
  </code></pre>
  
  <p>My <code>index.js</code> with code that uses UMM string definition:</p>
  
  <pre><code>  convo.threads['identification'].addQuestion('#identification_cpf', [
      {
        pattern: /(\d+)/i,
        callback: (response) =&gt; {
          convo.set('cpf', response.match)
          convo.next()
        }
      }
    ])
  </code></pre>
  
  <p>Result:</p>
