title: Bitbucket merge won't update master branch
body: <p>I am trying to get familiar with <strong>GIT</strong> and <strong>Bitbucket</strong>.<br>
  I've firstly created a <code>master</code> branch and then pushed all to it(<code>add origin..</code>), since I already had some stuff done in my project.</p>
  
  <p>Then my commands looked like this:</p>
  
  <pre><code>git branch dev
  git checkout dev
  </code></pre>
  
  <p>Do some work..</p>
  
  <pre><code>git add . -A
  git commit -m "Some work done"
  git push -u origin dev
  </code></pre>
  
  <p>Back to master..</p>
  
  <pre><code>git checkout master
  git merge dev
  </code></pre>
  
  <p>The problem is, that since folders on my computer are now in sync both on master and dev branches, the master branch on Bitbucket is still not updating and it's the source i've uploaded initially.<br></p>
  
  <p>Thanks for any advice!</p>
