title: Event Data Collected by Firebase Analytics DebugView Is Incomplete
body: <p>I'm sending events to Firebase Analytics and find out that part of the event parameters is missing in DebugView.</p>
  
  <p>Below are two identical events sending to Firebase and I've checked that all the parameters are there in Xcode debug console.</p>

  <p>The missing parameters seem to be random. Sometimes there's no custom param at all, only auto-collected data.</p>
  
  <p>Is there anyone also encounters this problem or does anyone know what causes this?</p>
  
  <p>I'm using FirebaseAnalytics (= 5.8.1)</p>
