Duplicate image error

Hello, I’m using free version of this plugin, currently using ver 2.4.7.
I put the shortcode inside WPBakery Page Builder using WP Text, this is my code:
[instagram-feed num=5 cols=5 imageres=auto showbutton=true showfollow=true imagepadding=0 background=#1b1b1b buttontext="Load more photos" showheader=false]

When the plugin loads images from my instagram, some images loads correctly, but some images get duplicated. You can check on the footer area of my website, or you can check the images I provided here: error image

Any solution?
