Python/Bottle template weird behavior when generating html table

I've followed few tutorials (bottle one as well), but my code ain't working as supposed to. Basically I'd like to have a html table generated in this way:

template is served in this way:

return template('template', data=result)

Snippet of code from my template:

%for item in data.data:
  %if ("X" in c_label and "Y" not in p_label and "Z" not in p_label):
  <tr>
    <td>{{child}}</td>
    <td>{{parent}}</td>
  </tr>
  %elif ("X" in c_label and "Y" in p_label):
  <tr>
    <td>{{child}}</td>
    <td>{{parent}}</td>
  </tr>
  %elif ("X" in c_label and "Z" in p_label):
  <tr>
    <td>{{child}}</td>
    <td>{{parent}}</td>
  </tr>
  %elif "W" in c_label:
  <tr>
    <td>{{child}}</td>
    <td>{{parent}}</td>
  </tr>
  %elif "U" in c_label:
  <tr>
    <td>{{child}}</td>
    <td>{{parent}}</td>
  </tr>
  %elif "Z" in c_label:
  <tr>
    <td>{{child}}</td>
    <td>{{parent}}</td>
  </tr>
%end
</table>

The problem is that python keeps running the for cycle even after %end. I've seen it in the generated page:

<table>
  <tr>
    <td>U</td>
    <td>I</td>
  </tr>
</table>
  <tr>
    <td>X</td>
    <td>U</td>
  </tr>
</table>
  <tr>
    <td>U</td>
    <td>I</td>
  </tr>
</table>

So for some reason it keeps ammending the </table> per each iteration which ofc totally screws the final page :).

Thanks in advance!

Solution

Thanks to kwinkunks I've identified this as a SimpleTemplate engine.

The answere is here: http://bottlepy.org/docs/0.11/stpl.html

e.g:

<div>\\
 %if True:
<span>content</span>\\
 %end
</div>

So as kwinkunks suggested, if must be ended with end as well.
