title: Build History Missing in Jenkins
body: <p>I just set up a new Jenkins instance for my project (Version 2.19.4). But when I try to generate several builds for testing I find that the Build History only shows me one historical build.  </p>
  
  <p>Before upgrading, it showed at least two or more. Is there a place in Jenkins I can set the number of historical builds which should show up?</p>
