Syngency plugin, code problem

Hi,

I just installed plugin called Syngency, support is not quite good with fixing these problems, but I have error duplicated code

<!-- default model template -->

<div class="syngency-model">

	<!-- Model Name -->
	<h2 class="syngency-model-name">{{ model.display_name }}</h2>

	<!-- Gallery Links -->
	<ul class="syngency-model-galleries">
	{% for gallery in model.galleries %}
		<li>
			<a href="#{{ gallery.url }}" {% if forloop.first %} class="active" {% endif %}>
				{{ gallery.name }}
			</a>
		</li>
	{% endfor %}
	</ul>

	{% for gallery in model.galleries %}

	<!-- Gallery -->
	<div class="syngency-model-gallery" id="{{ gallery.url }}" {% if forloop.first == false %} style="display:none" {% endif %}>
		<h3 class="syngency-model-gallery-name">{{ gallery.name }}</h3>
		<ul>
			{% for file in gallery.files %}

				{% if file.is_image %}
				<li class="syngency-model-gallery-image">
					{% if options.link_size %}
					<a href="{{ file.link_url }}" rel="{{ gallery.url }}">
						<img src="{{ file.image_url }}" alt="">
					</a>
					{% else %}
						<img src="{{ file.image_url }}" alt="">
					{% endif %}
				</li>
				{% endif %}
			
			{% endfor %}
			
		</ul>
	</div>

	{% endfor %}

	<!-- Measurements -->
	<ul class="syngency-model-measurements">
		{% for measurement in model.measurements %}
			{% unless options.measurements contains measurement.name %}
		<li>
			<span class="label">{{ measurement.name }}</span>
			{% if measurement.imperial %}
				<span class="value imperial">{{ measurement.imperial }}</span>
				<span class="value metric">{{ measurement.metric }}</span>
			{% else %}
				<span class="value size">{{ measurement.size }}</span>
			{% endif %}
		</li>
			{% endunless %}
		{% endfor %}
		{% if options.measurements contains 'Hair' and model.hair_color %}
        <li>
            <span class="label">Hair</span>
            </li>
            <li>
            <span class="value">{{ model.hair_color }}</span>
        </li>
        {% endif %}
        {% if options.measurements contains 'Eyes' and model.eye_color %}
        <li>
            <span class="label">Eyes</span>
            </li>
            <li>
            <span class="value">{{ model.eye_color }}</span>
        </li>
        {% endif %}
	</ul>
