This minimal example will trigger the bug. Removing the width attribute makes the problem go away. So it looks like the trigger for the bug is a nested table with a width attribute.

<wp:document xmlns:wp="urn:ns:wordinator:simplewpml">
  <wp:body>
    <wp:table>
      <wp:tbody>
        <wp:tr>
          <wp:td>
            <wp:table width="100%">

            </wp:table>
          </wp:td>
        </wp:tr>
      </wp:tbody>
    </wp:table>
  </wp:body>
</wp:document>
