title: Sitecore List Manager: add new contact
body: <p>I'm trying to add new contact to empty list in Sitecore List Manager. I click "Create and add new contact", type appropriate data and click "Save" button. After that I get following messages:</p>
  
  <blockquote>
    <p>Please note that this list is currently being built and is locked. </p>
  </blockquote>
  
  <p>and </p>
  
  <blockquote>
    <p>Please note that contacts in the list are currently being indexed, so not all contacts are available to view at this time. 0 out of 1 contacts are currently indexed. </p>
  </blockquote>
  
  <p>Then I use "Index manager" and rebuild "Sitecore_list_index". After that, I go back to List Manager and unlock list manually. </p>
  
  <p>Finally, I can't see any contacts in the list. Can't figure out what's wrong. </p>
  
  <p><strong>EDITED</strong></p>
  
  <p>Sitecore version is 8.1 (it was upgraded from 8.0)</p>
