Not sure if it's related but your closing </ul> is outside of the {% endif %} but the opening <ul> is inside the {% if %}

It's just my copy/paste mistake.

I can't reproduce this bug. Formatting worked with your example code. Anyway you should move up your into the first part of the if to get valid HTML.
