title: Firebase analytics events don't show value
body: <p>I have a game and I want to send event every time user sets new high score, I check if current score is > that previous and if it is I send that new high score to firebase. code:</p>
  
  <pre><code>Bundle bundle = new Bundle();
  bundle.putLong(FirebaseAnalytics.Param.LEVEL, extras.getInt("score"));
  mFirebaseAnalytics.logEvent(FirebaseAnalytics.Event.LEVEL_UP, bundle);
  </code></pre>
  
  <p>This is how it looks like in firebase console: <a href="http://i.stack.imgur.com/APLWK.png">image link</a></p>
  
  <p>You can see how events are grouped by their value.</p>
  
  <p>Problem is that i have 4 different modes and I want to capture high scores for each, so this is how I tried that:</p>
  
  <pre><code>Bundle bundle = new Bundle();
  bundle.putLong(FirebaseAnalytics.Param.LEVEL, extras.getInt("score")); 
  mFirebaseAnalytics.logEvent("mode4level", bundle);
  </code></pre>
  
  <p>And this is what I get in firebase console: <a href="http://i.stack.imgur.com/tCq3u.png">image link</a></p>
  
  <p>Grouped events by value are missing, I have only Event Location, Event demographics, Events per session.</p>
  
  <p>How can I fix that, key part of analytics is missing ?
  Thank you.</p>
