Plugin conflict with Vlog Theme

There seems to be a conflict with this plugin with Vlog Theme https://themeforest.net/item/vlog-video-blog-magazine-wordpress-theme/15968884 – one of the social media icons is showing huge on the cover of the theme of each post so distorting the whole cover of each post. I have had to deactivate the plugin unfortunately. Its a pity because it looks like a great plugin
