Joomla 3 - Virtuemart - Virtuemar product module - php

Question

I'm using Joomla 3 and Virtuemart 3.0.18.
I'm building a website to show products of my store. So, I created 2 modules in the same type: mod_virtuemart_product. I need one of them display my newest products and other display featured products.
My problem is my website just display one of them in a same page.
Please help me! Thank you so much!
Update:
In my template, I load those modules using like this:
<?php if ($this->countModules('modpro')) : ?>
<div class="modpro">
<div class="container">
<div class="row">
<div class="col-md-12">
<jdoc:include type="modules" name="modpro" style="xhtml" />
</div>
</div>
</div>
</div>
<?php endif; ?>
<?php if ($this->countModules('modnew')) : ?>
<div class="modnew">
<div class="container">
<div class="row">
<div class="col-md-12">
<jdoc:include type="modules" name="modnew" style="xhtml" />
</div>
</div>
</div>
</div>
<?php endif; ?>
I tried setting them in the same position, but it doesn't work.
I disabled one of them, other were be renderred. I set them on difference pages, them were be renderred.

Thanks everyone who viewed this question.
I has found the reason of my issue. In the sortSearchListQuery() function of the VirtueMartModelProduct class, I found these code line:
if(self::$_alreadyLoadedIds){
$where[] = ' p.`virtuemart_product_id`!='.implode(' AND p.`virtuemart_product_id`!=',self::$_alreadyLoadedIds).' ';
//$where[] = ' p.`virtuemart_product_id` NOT IN ('.implode(',',self::$_alreadyLoadedIds).') ';
}
It prevent my second module from loading the same products again.
So, thank you again!
