title: GitLab CI/CD unset variables set in CI / CD Settings
body: <p>I'm running a gitlab job and in the job I'm trying to unset certain variables set in CI / CD Settings.</p>
  <p>For example, I have
  <code>SOME_VARIABLE</code> set to <code>&lt;some_value&gt;</code></p>
  <p>Then, in the job definition, I'm trying</p>
  <pre><code>
  variables:
     SOME_VARIABLE: ""
  script:
      - echo SOME_VARIABLE - [%SOME_VARIABLE%]
  </code></pre>
  <p>But in the job itself I'm still getting</p>
  <p><code>SOME_VARIABLE - [&lt;some_value&gt;]</code></p>
  <p>instead of</p>
  <p><code>SOME_VARIABLE - []</code></p>
  <p>Has anyone came across this?</p>
