title: Sharepoint - Field appears twice on View / New Item
body: <p>I have a problem in a SharePoint list - some fields appear twice on the Display form, New Item form and on the list settings page. Both fields have the same ID and the same property page (same URL), so hiding one hides the other.<br>
  Using <a href="http://www.codeplex.com/spm" rel="nofollow noreferrer">SharePoint Manager</a> I can only see one field, but maybe I looked at the wrong places?
  Has anyone experienced something similar, and how can I solve this issue?</p>
