title: Google Analytics custom report shows zero pageviews
body: <p>I've created a custom report with dimensions: </p>
  
  <pre><code>Event Category, Event Label, Page Title
  </code></pre>
  
  <p>And want to see this metrics:</p>
  
  <pre><code>Total Events
  Pageviews
  Avg. Time on Page
  </code></pre>
  
  <p>Also, I applied a filter by event category.</p>
  
  <p>I see my report with some values in <strong>Total Events</strong> column, but <strong>Pageviews</strong> and <strong>Avg. Time on Page</strong> are always zero. What is the problem?</p>
