title: Google analytics dimenson values are random guids
body: <p>I am setting a custom dimension in GA with right index</p>
  
  <p>window.ga('set', dimension5, value);</p>
  
  <p>The value I am setting is <code>true</code>, <code>false</code> &amp; <code>error</code>.</p>
  
  <p>But when looking at the Google analytics dashboard I am getting some other values as well which are random guids, like:</p>
  
  <pre><code>(19dc2e4a-50cb-42ad-bb37-aa3129a72bcf,636229408930000000)
  </code></pre>
  
  <p>I am not setting those values but how am I getting those?</p>
  
  <p>Here is the code snippet.</p>
  
  <p>Hi Tony, thank you for getting back. I have done GA dimensions in past and have never experienced this problem. Dimension5 is a brand new dimension we have created and it has never been used in past. </p>
  
  <p>My code looks like this.</p>
  
  <pre><code>variantAssignment.getVariant(contextId, success, failure);
  
  function success(){
      if(response.data.variantName === 'WithTrue')
          sendGaEvent("true");
      }else{
      sendGaEvent("false");
     }
  }
  
  function error(){
    sendGaEvent("error");
  }
  
   function sendGaEvent(value) {
     googleAnalyticsService.setDimension("dimension5", value);
   }
  
  The code in GoogleAnalyticsService looks like this.
  
  function setDimension(dimension, value) {
     if (window.ga !== undefined) {
        window.ga('set', dimension, value);
       }
    }
  </code></pre>
  
  <p>And in the dashboard, my report looks like this.<br/></p>
