title: SharePoint Task list column naming
body: <p>So I add a few columns via Web UI, I named them Number. When I list tasks in that list using <code>GET https://graph.microsoft.com/beta/sites/{site-id}/lists/{list-id}?expand=columns,items(expand=fields)</code> : I get:</p>
  
  <pre><code>...
     "items": [
      {
          ...
              "v2bs@odata.type": "#Single",
              "v2bs": 1,
              "_x0077_fx0@odata.type": "#Single",
              "_x0077_fx0": 2,
              "ziyy@odata.type": "#Single",
              "ziyy": 3,
              "m4l2@odata.type": "#Single",
              "m4l2": 4,
              "id": "1",
              "ContentType": "Task",
          ....
          }
      }
  ]
  </code></pre>

  <p>Every time there are different names, and also some of them are not allowed when I try to create a new task(<code>POST https://graph.microsoft.com/beta/sites/{site-id}/lists/{list-id}/items</code>) with the same properties to the same list. Is this just a random naming? And how can I get the title of a column?</p>
