title: Firebase Analytics: Event is shown without values
body: <p>I am trying to use some of the events which are already predesigned in Firebase Analytics - e.g. the view_item. I implemented that like this:</p>
  
  <pre><code>Analytics.logEvent(AnalyticsEventViewItem, parameters:
          [AnalyticsParameterItemCategory : "Test" as NSString,
           AnalyticsParameterItemName : ASINcode as NSString])
  </code></pre>
  
  <p>When I check debug view, it looks like this:<a href="https://i.stack.imgur.com/KfcEb.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/KfcEb.jpg" alt="enter image description here"></a></p>
  
  <p>The problem is, that I cannot find those parameters I attached in the Analytics Event - I see that it was triggered, but the ItemName is not available. If I go to "add event parameters" - it shows my parameters I attach, but after adding them as text, it looks like that:</p>
  
  <p><a href="https://i.stack.imgur.com/3PfRC.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3PfRC.jpg" alt="enter image description here"></a></p>
  
  <p>I did this code already several days ago - so the delay should not be a problem. It also tracks the events, but the values are not there.</p>
  
  <p>I already searched for some info on Stackoverflow and checked the tutorials and howto from firebase, but I don't really understand what is going wrong.</p>
  
  <p>As shown in the tutorials, there should be automatic charts with the parameter values. I also checked that all not optional parameters are included.</p>
  
  <p>I would be thankful for every advice or idea you can provide me with.</p>
