Porto’s Socialfeed instagram – How to always get 4 images in 4 columns?

Is there someone familiar with Porto’s Socialfeed instagram module?
By default the module is always showing 6 images in 6 columns.

I only want to show 4 images, but when I select 4 it is showing 4 images in 6 columns. this doesn’t look right. Does someone know how to achieve this? the module only contains a .phtml file

This is the source .phtml

  <?php
$_enable = $this->getConfig('sw_socialfeeds/instagram_photos/enable');
if($_enable==1){
    $accesstoken = $this->getConfig('sw_socialfeeds/instagram_photos/accesstocken');
    $count = $this->getConfig('sw_socialfeeds/instagram_photos/showing_counts') + 1;
    $padding = $this->getData("padding_item")!=''?'padding:'.$this->getData("padding_item").';':'';
    $template_type = $this->getData("template_type");
    $media_type = $this->getData("media_type");
